I have been using 22g or 23g pins do you think warming it might work? I feels hard under the shin where i stuck my self like i lump under the skin. i will try one more shot and go really slow. i can't keep dealing with this type of pain i don't even feel like working out. i did my last shot in my leg and it hurts to walk. i know when i take the winny i don't feel anything at all the next day feels fine. has anyone tried to warm theres up did it work any for them
