Hi Doctor; I have been having tingling of my fingers and warmth to the soles of my feet as well as my hands sometimes; my doctor prescribed Horizant 600 mg. daily (30 tabs), then gabapentin, 300mg. twice a day (60 tabs.);. I ve completed both. My problem lessened but periodically, slight cramping of hands and warmth to the feet as well persist; not like before, but not totally gone. Treatment has been completed since two days. What would you suggest.
