Don't stop with just one doctor visit. If it is not circulation, It could be neuropathy or other problems. If your doc does not want to follow up try another doc. Soon. <br />
Please. I would try a specialist. Often your general practitioner may not see a particular issue often enough to recognize it right off. Many conditions can be corrected easily. There are some that can not be reversed if allowed to go on for too long. Best wishes
Go to the doctor, could be as simple as circulation problems, but probably need to get it checked out if it happens more than once or lasts more than a few seconds.
Sorry, I am no medical professional, but sounded like my mother-in-law's complaint and she is having circulation problems. Listen to these other guys, they may know more than I.
