I am sorry to hear of your pain. Many people will be able to help you and offer support on these boards (I am new too). I was on Neurontin for a while but the side effects for me were too bad. I tried many meds and the only one that has helped me at all is Oxycontin, but different meds work in different ways for different people.
I hope it can offer you some relief, I believe it has helped many sufferers, it is just a case of finding what works best for you. I also find Clonazepam helps with my muscle tremors and interestingly my balance.

Take care and stay strong
Jo
