Problem: My friend missed a vein while shooting Subutex, she used a vein that was located between her wrist and her elbow and had about 60cc's under her skin. When she missed almost immediately she began to lose feeling. The numbness ran all the way to her fingers and trying to pick up even as much as an empty water bottle was painful. She couldnt move her wrist or her arm very well and she also had trouble spreading and clenching her fingers. The pain was almost unbearable.
Solution: When she got home she got a bucket of water and filled with ice and took 400mg of ibuprofen in case of swelling. She stuck her forearm in the ice for as long as she could and had to take it out occasionally but overall she had it in there for over twenty minutes. After this what seemed to be a soon doctors visit was reduced to minimal pain and numbess and was able to move her arm. She still has time to see if the pain will come back but the bucket of ice helped a whole lot.l
Edit: she was startled by a loud noise and accidentally slammed 60 units (not cc's into her wrist along with the needle. the shot was not intentional.
