HI, I scratched my left inside forearm on a rusty nail 4 days ago. The area is slightly red and raised around the scratch with tiny little raised bumps. I cleaned it thoroughly and put neosporin on it. I had a tetanus 5-6 years ago. Is this a sign of infection? Should I  have another shot?
Thanks to Chat Doctor I can understand your concern on scratching there may be inflammation redness and swelling due to inflammation don't worry, anyway you cleaned it and antiseptic powder you applied just wait for 2 days, if not subsiding then start anti-inflammatory Chat Doctor. don't worry it may subside, take TT in. Further dose in safety please cut your nails and make them clean .ok try to avoid scratching .
