Choices That We Make

It seems I now fully  recovered my pre-trip form. I'm not quite back to the shape I was in back in the summer, but  I did manage 8000 steps in a 3 hour jaunt yesterday. I went for a haircut in Sunset, stopped in Mission to buy some fruits and then carried 10 lbs of it  to an open house for rental.

The prices have been going up in leaps and bounds in SF. The cheap haircut that used be $12 is now $15. And drip coffee from Peet's is now over $2, and Philz went up from $3 to $3.50. The Muni fare went up to $2.50 as well. It must be the effect of the rising minimum wage. It is now $13 and scheduled to go up to $14 in 6 months on its way to $15 next year. No complaint though. People in SF can afford it and I'm all for living wage. Not that you can make living in SF with $15/hr wage, but the more the better.

Coming back from Sunset, I just missed the muni train. I was about to turn the corner when the car arrived. I jogged for about 20 meters thinking I might be able to catch it. When I came around the corner, I realized the stop was still another block away. If I was healthy, I could've continued to jog and caught it just fine. But I was risking getting sick for 4 days if I did that. So the choice was between that and waiting for 10 minutes for the next train. I obviously chose the latter. This is the kind of choices that we CFS patients face on daily basis.

Then I woke up this morning with this fantastic fatigue. I used to get the same kind of fatigue the day after I climbed the Mulberry tree in the front yard of my old house in San Jose to prune it. It used be an all day affair. I would cut the branches off with my chainsaw for 30 minutes or so, take a break for a while and repeat. Then haul the debris to the curb for the green waste crew to pick up the next morning. Now I get the same fatigue after just running errands. It is not a post-exertional sickness though. It is a post-exercise fatigue accompanied by happy feeling. I'll have some post-exercise funk tomorrow when the happy chemical dissipates and recover just fine.

Cross-Country Trip Plan

Now that I'm out of the prison that was the post-trip struggle, the desire for the cross-country trip is stirring again. This plan was conceived based on the observation that when I move to a new place I tend to walk further without getting sick. So why not move around and see what happens? The plan also got to do with the fact I'm fairly useless since I'm not working, so I may as well make a good use of my down years and travel around.

That was why I moved to Seoul for a few years.  I not only got to see the country that I haven't seen in decades, I also found an eminently walkable city. SF was swell, but I walked all over it and I was in need for new, exciting routes by then.  Moving was a breath of fresh air and I was practically in a disneyland.

The trip across the US won't be the same. For one, it is of a vastly larger scale. I won't be able to make much of the trip since I'll have to limit my walking to 1 mile per day. No way I can fully see national parks with that. But it will be exciting enough nonetheless and that may prove to be enough.

The thanksgiving trip to Socal has put a damper on the plan, however. If I  have to pay with 6 weeks of struggle for a week of romping, it just won't be worth it. I'll have to strictly stick to the limit and do not walk more than a mile a day and give a full rest every 2 days.  And we'll have to stay put in one place longer. Beyond that, I'll have to play by the ear listening to my body very carefully.

Tesla opened up its flagship store last summer just a few blocks from my apartment. I was already on the waiting list for the Model 3, so I figured I'll pay them a visit and test-drive their current model. I liked it so much I switched it to Model S. More expensive, but it has a lot more utility.



It is a perfect car for a CFS patient. It must stop every couple hours and recharge for 30 minute or so. CFS patients need to stop and rest after every 2 hours of driving anyway so it is a perfect match. That should be enough to recharge me and I should be able to drive for extended period without stressing. Model S can actually fit a twin size mattress in the back with the backseat folded down. I could climb back and take a nap. Its Autopilot feature could relieve the stress of driving too, though it may kill if I become too complacent.

So my next plan is to travel around the country in a Tesla this summer. I'll check out of this horribly expensive city for a few months and the saved rent alone will finance the trip. The fuel cost will be zero since the use of  Tesla chargers is included in the car's price, so the cost will be only lodging and food. If you don't count the price of the car, that is.

That is all 6 months way, anyhow. For now, I am going to try to replicate whatever I was doing before the improvement appeared back in June. They are:
  • No Internet, commute to Peet's for the connection
  • Strict brown rice diet
  • Isometric exercises
  • Sudafed, twice a week
I went through my log again, and I noticed that I switched isometric exercises from pushups. I figured that would lessen the muscular microtear and therefore possibly lessen the post-exertional sickness.  I didn't feel any difference so I went back to regular pushups soon after the improvement appeared. I don't know if that was the reason for the improvement, of course, but I'll add it back to the mix and see what happens.

Chances are all these are no more than coincidences. And if you put them to the test, they are likely to not work for you, just like none of the methods reported by other patients worked for me.

Post-Trip Struggle vs. Post-Exertional Sickness

And just like that, the post-trip struggle appears to be over. I spent 3 hours grocery hopping (yes, shopping hopping) 2 days ago, with over a mile of walking in total, and I didn't get sick.  In fact I've been feeling pretty good. Under the circumstance, that is. It's been 6 weeks in the post-trip jail in all.

It is the same amount of time, by the way, that I used to spend wallowing in over-training syndromes when I was training for Judo competitions. I used to kneel over for 6 weeks at a time when I over-train. Coincidence? perhaps. Or maybe the post-trip struggle is equivalent to the overtraining syndrome. The struggle after the trip to Korean eastern and southern seaboard in 2011 was also about the same length.

This post-trip struggle is also remarkably similar to the struggle I had after the flu shot in 2015. The flu shot is known to cause low grade inflammation, so I surmised that the inflammation lasted for 2 weeks. But the paper on the effect of flu vaccine on inflammation marker found no sign of elevated inflammation on day 7. So the 2 week struggle after the flu shot is not fully explained by the inflammation. If not the inflammation, then it must be the sensitivity to inflammation that went up.

Is the post-exertional sickness also the increased sensitivity? It lasts 2 to 5 days, with most of them 3-4 days. And it coincides with DOMS and lymphocyte activation . The lymphocyte activation, like DOMS, could be the response to the muscle fiber damage. Since muscle fiber damage causes inflammation, the post-exertional sickness is likely caused by the inflammation rather than the increased sensitivity to inflammation.

The accumulation could be likewise. Since the response to an exercise can last for 4 days, it is not unreasonable to assume that the damages from exercise accumulate over that 4 day window. And if the accumulation goes over the threshold, the post-exertional sickness sets in.

In summary, a prolonged period of activities raises the sensitivity to inflammation and therefore you become more likely to get sick. The accumulation crash, on the other hand, is caused by the accumulated damage from the activities. It is the inflammation, not the inflammation sensitivity.

Finally, the post-exertional sickness itself is the sickness behavior triggered by the inflammation in CFS patients who are inflammation-sensitive.

At least, that is my theory.

Theory For Post-Trip Struggle

Now it's been almost 6 weeks and I'm still struggling. I can only manage a mile every other day. And I'm back to logging ADL (activities of daily living) because they have effect my condition next day. I'm not a happy camper.

There are two possible explanations for this post-trip struggle: 1) it's taking a long time to recover from the damage caused by the trip; 2) the body has recovered, but the sensitivity to exertions/inflammation went up because of the trauma caused by the trip.

Repairing the damage from exercise should not last more than a few days. Delayed onset of muscular soreness only lasts 3 to 5 days and so does the immune response to an exercise. So, the prolonged inflammation, if it exits, must be from the accumulation of oxidative stress.

Searching for oxidative stress and prolonged inflammation turned up a paper on oxidation-inflammation theory on aging. It states that chronic oxidative-inflammatory stress prevents adequate homeostasis and therefore the health. (I always thought that CFS is strikingly similar to aging, and this paper fits in with that). But it does not state that accumulated oxidation damage causes prolonged inflammation. It only mentions the homeostatic deterioration caused by oxidative-inflammatory stress as the cause of aging, which probably only means oxidative stress and inflammation happens together. I couldn't find any paper that says accumulated oxidation damage causes prolonged inflammation after the stress is over.

So, on to the second possibility.  If the inflammatory response to the damage from an exercise should not last more than a few days, the post-trip struggle cannot be caused by the damage, or accumulation of it. Instead, the prolonged stress must have raised the sensitivity to inflammation. If you are more sensitive exertion and ensuing inflammation, you are more likely to get post-exertional sickness. And the oxidation-inflammation paper works better with this theory: the stress caused the homeostatic thermostat to become more sensitive.

One may think that it does not matter weather it is the inflammation itself or the sensitivity to inflammation. The end result is the same: you are weaker and you are more likely to get the post-exertional sickness. But you can always recover from the inflammation with rest. The increased sensitivity, however, is a fundamental worsening of CFS and there is a possibility that you may not recover. It is a re-injury. Post-exertional sickness that lasts a few days, on the other hand, probably doesn't make CFS worse fundamentally. It is a terrible nuisance that robs the quality of life, however.

The lesson is that prolonged or traumatic activities can worsen your CFS fundamentally and therefore should be avoided at all  cost. But I already knew that, of course. I have plenty of experience. Back in 2008 when I felt better, I went on a biking trip only to seriously worsen my condition for a year. Then, I climbed up the Telegraph Hill in 2009 while self-practicing the Graded Exercise Therapy. My condition get seriously  worsened again till 2011. It's  been very, very slow improvement since then.

I went on this trip knowing the danger because the last trip went well. Two and a half years ago, we stopped in Philippines for 5 days on the way back from Korea and did some snorkeling. Unfortunately, I don't have any objective data to compare because I only started wearingg Fitbit since 2015. Looking back though, it probably was easier trip. It consisted mostly sitting on the planes and buses. The little activities that I've done was basically floating on the water. And it included one full day of rest doing absolutely nothing in the hotel.

And this is the danger of going by the memory and subjective feeling. You managed 7,000 mile trip, so you think you could manage 1,000 mile trip.  But I probably walked much more this time. And that was beside all that driving.  I'll have to limit my next trips to 5 days at a time, with a full day rest every two days, and no more than 6000 steps of walking each day.
