Hi Brenda, I have had intense shooting pains in my feet and legs as damaged nerves started funtioning again. Each specific area only happens a few times of a few minutes duration so depending upon the pain it could be connected. Reinnervation has been painful for me, especially my formerly numb feet and certain areas of my legs. I have never had such pain as you describe in my calf. Is that where blood clot pain occurs? Are there other symptoms like swelling? One has to be careful. Sometimes its tough to know what to ignore.
