I am 44, weigh 145 lbs and have no real medical history, but my question is I continueously am losing my second toenail due to getting a blister under the nail. This happened again recently and instead of wait for the toenail to fall off by itself I cut it down so it wasn't just hanging there and clipped away the skin from the blister. Now my toe won't stop throbbing. Why does it throb?
