Depending on the protocol the HBOT center is using, 10 might not be enough to really determine if they're helping. I didn't experience much change until we started diving deeper, faster. Ultimately, it cleared up an area I had spread to, but didn't change my original site--although swelling was reduced. I would encourage you to attend pt, swim in a warm pool, do yoga or tai chi, have massages, go to infrared saunas, if at all possible, during the same time period. Follow the CRPS diet. Take high doses of Vit C and if you respond well to steroids, start a course maybe after your 3rd or 4th dive. Reduce as much stress as possible and make it a period of time where you're truly focused on healing.
