A Neurologist I visited advised me that I had a Tarlov cyst on the s3 & s4 that caused the pain with sitting and that nothing could be done to resolve this. Hence a life of pain when ever I sit down. This diagnosis was given 2 years ago and since than I have had quite a few conditions that came to light through bone scans, MRI's CT Scans and ultra sound. Such as degenerated disc disease at the L4, L5, S1, and Sacro-Iliac, Hamstring Tendonopathy at the high origion on the left and right side, a femoral hernia, Pudental neuralgia and prostatitis. I have received treatment to all of the above but nothing has helped me so far. Writing this post I am still sitting in pain and am desperate for a solution.
