Hello! On 11th april i suffered explosive injury on my hands-fingertips to be precise. It was an aluminum fuze which went off in my hands and blew off parts of my left index finger and thumb,injuring 3 more on the right hand. I have received tetanus protection along with heavy antibiotic treatment after the injury,and wounds healed nice-as possible. A month ago,from my right index finger,on a part which healed well,but was kinda swollen the whole time since that faithful day (in the middle of fingerprint),a hole appeared,and white pus came out-all of a sudden. A couple of weeks after that-i pulled out a piece of aluminum out of the newly appeared wound. What troubles me now,is that the wound is still kinda opened,fingertip hyposensitive,with formed callosity-but with smelly greenish puss coming out every couple of days. And-a new hole appeared 5mm from the first one,also with oozing puss. Is that normal for an unprotected wound or there could be other processes developing(such as gangrene,deep tissues infection,or a part of foreign object still logged in under my fingertip)?
