There is a well known dr. Dr. Forrest Tennant from Calif. retired. He mentioned Blood Patches, not to get them. He started Arachnoiditis Federation. I read about B. P. before. May I suggest, until you find a dr. who is well versed in the disease, to be very careful making your decisions. It upsets me when I hear again these medical biggies and they are never responsible. Please be careful. Try and get as much information as you can. You have to also be educated about AA. Let drs know you have researched the disease so they know you know what you talking about. Good luck to you
