Garzie: That explanation really helps narrow down my treatment plan. I'm fairly certain now that my remaining symptoms are due to left over damage and not from persisting infection. I'm going to focus on strengthening/protecting mitochondria and helping along the antioxidant cycle.
So with PEM, mitochondria can be functioning quite well until there is oxidative stress brought on by exercise. I wonder why it doesn't really hit me until the next day though. I might start feeling a little heaviness in my chest and a little tightness in my throat a few hours after.. used to get brain fog as well shortly after. But the fatigue doesn't really hit until the next day, and it lasts for at least 3 days (sometimes much longer).
Might the delay indicate that lactic acid build up is playing a part? How does the onset of your PEM compare to mine?
i don't think what causes the Post Exertion Malaise is fully understood yet.
i have seen studies in the CFS literature where PEM is usually described trying to track inflammatory markers before during and after exercise but from memory, i have not been fully convinced by these.
people like Sarah Myhill speak of damaged mitochondria burning energy less cleanly when damaged - and thereby creating more free radicals by-products that do further damage as one mechanism for it. but again i think this was part theory and not 100% proven
it may simply be another manifestation of the so-called cell danger response - that shuts the cells energy production down to protect the cells from further damage - but again I think 100% proof may be lacking.
if anyone has read anything more definitive would be interested to hear
clearly it's linked to people suffering fatigue and doesn't need to be a physical exertion that brings it on.
driving or socializing would also trigger it for me. less so now but i still have to be careful.
the reason for the delay doesn't seem to be well explained also - but I have read that the longer the delay - the worse the underlying condition may be and this seems to hold true for me - as in the past it would sometimes be even 2 days after the exertion that symptoms peaked - now I tend to start to get them later the same day and peak the day after.
typically now mine is 50% better after the first day - 50% better again the next day and then pretty much gone the next. but depends on how much I have overdone it.
i think healthy fats may be critical to repairing the mitochondria - as well as removing the insult/infection that initially caused the problem. the membrane across which the energy is generated in the mitochondria is made from these and damaged lipids are known to stick in that layer and interrupt its function.
for me, that is clean high-quality fats from sources such as
grass-fed organic beef, lamb etc ( anti-inflammatory fats and Omega 3 etc )
organic free-range eggs ( phospholipids )
oil fish
