I have peripheral neuropathy, PAD and scleroderma with Raynaud's of fingers and toes for 30+ yrs. previous finger lesions, now 3 toes of L foot developed gangrene. Nifedipine had been sufficient for Raynauds. Now added sildenafil, plavix, trental, hydroxychlorquine all to increase blood flow. Arteriogram with balloon could only open one artery. Slowly healing. Gabapentin 2100 mg in 3 doses. Recently having excruciating burning,jabbing pain at night. Feels like neuropathy but maybe worsening infected foot? Zonna
