Was doing some reading on the chronic pain forum this morning about adrenal fatigue:
http://neurotalk.psychcentral.com/thread156416.html (which apparently is medically spurious but widely talked about among holistic practitioners)
This led me to read more about adrenal insufficiency:
http://en.wikipedia.org/wiki/Adrenal_insufficiency
Apparently the pituitary and hypothalamic forms of adrenal insufficiency can be caused by head injury, and I have read some other articles talking about how a major cause of PCS and PTSD is how the hypothalamus gets rewired in a sort of haywire way.
I definitely notice some overlap with my symptoms such as fatigue and low blood pressure. Wondering if some of the temperature regulation difficulties, etc. could also come from something like this. Think I'll ask my doctor about this in the near future.
Has anybody had adrenal hormone workups and/or supplementation or other experience with this that you could share?
