if its an open wound get to the doctor if its not healing as you could end up with a secondry infection. ammonia, vinegar only work if the sting is fresh and only work with certain types of aquatic stings in some cases ammonia and vinegar can actually increase the absorbtion of the toxins into the body such is the case with blue bottles. so to use these methods now will only cause more harm than help. water or saline salution is the best thing now to flush out the wound and keep it dry if the area around the wound looks re and swollen its a sign there could be an infection already there so to be on the safe side get it checked out. if it helps i was stung by a jelly fish when young (hazard of living in the most dangerous place on earth) and it took almost 3 weeks clear up and still have the scare.
