Dear Sir, Good morning. I have some in thigh last one year. I have consulted many doctors they said surgery only one solution. I do not want to do surgery because no guarantee it will be success, as per my MRI report Dr. said My bottom side cushion is damaged. Left side bottom side bend to hip side. Due to that reason when you sit that cushion come out that touch in Vain. So immediately blood circulation stop. Start pain, Problem only when I am sitting. Back side thigh to knee part.
