I have had 3 HBOT treatments so far. The first one went great--went to 2.0 ATA and had no trouble--and the symptoms seemed better. Second day I went to 2.4 ATA and had a lot of trouble with deep cold pain for the rest of the day. The third treatment we went back to 2.0. This was yesterday. Today I woke up and it felt like every cell in my body was on fire. Burning pain is not even normally one of my symptoms, and I only have (had) RSD in my left foot and leg. If anyone has had experience with HBOT, please share and offer some advice on this. I have heard that things can get worse before they get better, but this whole body burning thing has me worried, and where my foot was numb before, now it's on fire. I think I like the numb better. This is about as bad as my symptoms have ever been. On top of it all, I'm having some cognitive problems. Just not feeling with it...distant, out of it, and tired but can't sleep. Just not myself at all. Very concerned. Do I need to work through this with more treatments, or should I assume things are going to get worse and stop now??? I'm scheduled for 40 treatments and I've only had 3...good grief, I didn't really foresee how intense this all would be.
