Though first pin was hot but not this much painful. 2nd pin was painless I dint feel anythg. This 3rd pin is really hurting. Needle size is 24 G. Yes it was pinned deep inside. (Full length)Did you inject to fast? Pull out to soon? What size needle are you using? Did you pin deep enough? Did you miss the muscle? There are a lot of reasons that can give you pain. Keep an eye on it and your temp
You can try keeping it elevated and put some ice on it. If it continues and gets worse ie really hot and you get a fever you might want to get checked out.
