Hi Joshua,
On one of the earlier incarnations of the MGH BrainTalk TOS board an RN named Heather Guhl was doing research into the use of HBOT for TOS. I believe she found it would benefit many TOSer's, though not all could tolerate it due to co-existing health conditions. She ended up working with an HBOT center or chain of centers, I believe in CA. Unfortunately, the expense isn't covered by insurance, and many sessions are usually required. And outside of CA, free-standing centers are hard to find.
However, if you have access to one and can cover the cost or get insurance to do so, I think it would be very beneficial.
Can anyone provide the link to the WayBack Machine and from there to the MGH forum archived posts from 2000 or so? I know those posts were from before I came (2003), but I used to prowl through them- many crashes ago.
It's a real shame so much valuable information was never recovered.
