It is unfortunate but true that many well respected surgeons do not "believe" in Tarlov cysts. I had one tell me that it was "hogwash". Wow. Well I am one week post-op from having the surgery to treat my cysts performed by Dr. Feigenbaum. The post-op pain is not nearly as severe as I had imagined. The recovery process is slow and and improvements in my symptoms are still pending but supposedly that is normal. Nerves need time to regenerate...much longer than muscle tissue.
