I was recently diagnosed with CRPS for the second time. i had it 18 months ago following a foot injury and it was successfully treated with 3 sympathetic blocks and neurontin. I fractured my tibia and now have it again. i have had 4 blocks and 2400 mg of neurontin but it has spread back to my other leg as well as the injured leg. Does anyone have any suggestions. I feel guilty being discouraged already - it has only been a few months. i am not sure I can deal with the pain again. the fracture was nothing compared to the CRPS.
