Shooting in crook of elbow, the needle went in. Kinda moved the needle around to find a vein and instantly felt a weird, fairly strong pain at the tip of the needle (maybe half inch below skin) and its been 24hrs and there's been a constant sore type of pain, like the pain from pulling or straining a muscle. It's the forearm muscle, right below crook of elbow. The pain is deep in there, can be felt more by rubbing the muscle in that spot. Flexing increases pain. Is it possible that a nerve was hit (would expect a more shooting electric pain in that case)? Or hit bone? Or moved the muscle in a bad way? It's not debilitating pain but I'm curious as to what could have caused it. Thanks in advance!
