I have a very rare spinal disease called adhesive arachnoiditis . i am wondering if there is any treatment?

Yes: First line treatment would be medications such as neurontin, lyrica, (pregabalin) or cymbalta. These have a beneficial effect on neuralgic pain. A more aggressive treatment could be used if pain relief from medication is inadequate. The most effective is spinal cord stimulation but an inter-thecal pump can also be tried. Finally, don't forget relaxation therapies usually taught by pain clinic psychology.

Arachnoiditis(spine): The symptoms of arachnoiditis can be treated with medications such as membrane stabilizers (like gabapentin), antidepressants and other pain meds. Dorsal column stimulation can also decrease its symptoms. Unfortunately, there is no cure or reversal of arachnoiditis yet...
