What causes pins and needles sensation in the heel when I stretch?
Patient: I am having pins and needles pain on the back of my left heel when i stretch too far, such as when I do downward facing dog in yoga. I have never had this pain before. Should I see a foot doctor? I think it has to do with my achiles tendon. The muscle is very tight and it only hurts when I stretch too far. Doctor: Hello,  Consult an orthopaedician and get evaluated. The possibilities are plantar fasciitis and neuropathic causes.  Hope I have answered your query. Let me know if I can assist you further.   Take care   Regards,  Dr. Shinas Hussain, General & Family Physician
