Debbie,
I'm sorry to hear this! Also, I am very sorry I don't have an answer for you and I sure wish I did! I know you tried HBOT, it is a major aid for me but has to be on going. Diet, water exercise, HBOT, suppliments, meds and meditation are my routine. I really wish I had the answer.
I'll keep you in my prayers.
Blessings,
Di
