Out of interest Suefew, what depth did your HBOT dives go to and how long were you in the chamber at this depth, and did you have the dives on consecutive days? I ask because, the MS therapy centres maximum depth is 33 feet and you stay in for an hour. This seems to be acceptable/recommended for ORN by the HBOT people at Ninewells Hospital in Dundee. However, the chambers at the private hospitals dive to a depth of 45 feet and you're under that pressure for a total of 90 minutes. (The difference may be significant given that the NHS in England & Wales changed their policy on funding HBOT April 2013, so that now they will only, if you're very lucky, fund HBOT at these private hospitals).
I realise that HBOT might not work for everyone and for others it seems to work exceptionally well (so many variables I suppose to do with dose of RT and how much damage has been done, how early its been caught etc etc).
Pleased for you that you have found you answer with Andrew Lyons.
