I work as a dog groomer and often get little, sharp hair stuck in my skin. I can usually get them out, but there seems to be one or more that have gotten stuck in between my fingers on my right hand. There is a large bubble and my entire hand aches. The bubble itself is soft and when touched feels like a sharp aching pain. I'm not sure what to do about it, but can't afford to go to the doctor right now because I don't have insurance. Is there anything I can do at home to cure this?
