Hi, yesterday I gave blood. The individual who took my blood had difficulty finding a vein, and had to go for a deep vein. When the needle went in, I felt this shocking that went down my arm. When the needle got out, I didn t feel anything. Last night and today, I have been having some tingle down the forearm, but only when I do a sudden move, put my hand up, or grip onto something hard for a long time. Will this go away, and is this considered nerve damage? What should I do
