Greetings: I am a missionary substance abuse counselor to a rehabilitation center in Corozal, Belize, C.A. We just had a new admission who developed a large, painful boil on his leg below the knee. I believe it is related to his drug use. He admits to cocaine, alcohol, and cannabis. He is being treated by a local medical clinic with antibiotics and ibuprofen for the pain. Is this related to his withdrawal? Is this the way the drug is seeking to detox through his skin? Patricia Consoli
