That is quite a robust CD4 count for someone who has completed chemotherapy. In terms of the neuropathy, it should get better in time.
Many drugs are available for it.
You may find out which is best for you only by trial and error. Many providers try Neurontin. That would probably be my next try if you are not getting relief from amitriptyline. Although I have not personally prescribed Stadol for pain-control, it is certainly a reasonable choice. I usually prescribe Fentanyl patches.
