Hi there,
I came across your message while searching for something else on the internet. So I just had to signup so I could reply to you.
I also have severe pain in the area of the ischial tuberosity. I have spend 5 years trying to determine what the issue is. I have tried the cortizone shots, warm bath water twice a day ( which did help), phy therapy (it helped as well) . Things seem to bring down the pain a bit, but never did it go away and it always got worse again.
I have had 5 mris, specialits across the crountry..and then..a radioligist told me to have an mri with contract. This type of mri will show if there is any growths in the sciatic notch or any where else around the nerve, inflamation,( same sort of things as a normal mri) however they are also able to tell if there is an increased signal. My mri results showed a diffused increase and at what location it was coming from.
To treat the pain i take percoset. 10-12 a day. alot. I am trying neurontin again - just started not sure how it will work.
I found a surgin that specializes in nervers. He has helped others with the same issue by fixing the nerve. here is his website: http://www.rosenbergplastics.com/peripheralnerve.html
Have you had an MRI with contract? If so what was the results?
One other thing, i use swedish bitters capsaicin cream. This is over the counter and really helps with the shoting nerve pain.
I hope my story and results help you, at least a little. I know when i was looking for answers, they were hard to come by.
