What causes pins & needles?
Tingling sensations can be caused by a reduced blood flow to the area, but also if their is nerve dysfunction. It is a symptom that is very present in neurological disease. Given that you have had a stroke, if would seem likely that your pins and needles are due to nerve dysfunction. There is also the possibility that the brain is malfunctioning making you believe that you have pins and needles. In terms of treatment I am not aware of an medication designed to treat this symptom per say, but some of the atypical pain killers (used for things such as phantom limb pain like gabapentin or amitryptiliine) might be of use, but there decisions best left to a neurologist!
