I would recommend that you get an EMG/nerve
conduction study to evaluate for signs of nerve
. You should also see a vascular surgeon for consultation on your peripheral vascular disease. Neuropathic pain medications such as Neurontin, Lyrica, Elavil, Pamelor, Maprotiline, Cymbalta, etc. are generally most helpful for pain associated with this type of damage.
I hope this has been helpful.
