Oh wow Satish I am so very sorry to hear this news. If it is any comfort, your experience tells me to be very careful with any ballistic stretch, where pressure is being applied to deepen the stretch.

I hava a tight piriformis, always have, I think from running. While seated I put my right foot over my left knee and bend forward slightly, and then reverse for the other side.

I had my hip replaced this March, and forgot about the post-op admonition to NOT bend more than 90 degrees at the waist. I did that 4 weeks after surgery, an IT band stretch I've been doing forever. The force yanked by brand new hip apart. The pain was excruciating but fortunately it was pulled back into place in the ER - no broken bones and the prostheses looks fine. Lesson learned.

I work with a trainer too and he is extremely careful in what he has me do. And my trainer never touches me, I just follow his lead. The fact that your trainer did this may be something you want to get legal help for. I'm sure that, like me, you like your trainer. But this simply shouldn't happen.

I'm at a loss for what to offer you Satish. I know you've seen a lot of Drs. Might help to see a neurologist if you haven't. I would also see what used to be called a Sports Doctor. Now they're called Doctors of Physical Medicine. I have one and she finds things even my specialists don't see.

I wish you the best friend. Medical science has come so far - have you tried contacting Mayo or the Cleveland Clinic? They have probably the best Drs in the USA, although you may have to travel to see them.

Take care of yourself Satish.
