A friend of mine got a tattoo 4 days ago (unprofessionally) and it is now swollen, flaking, and there are pits visible in the tattoo. He is vomiting, with accompanying fever and nausea. Are these symptoms of blood poisoning? He has no insurance, so if it can be dealt with at home it would be best, but if medical treatment is necessary, he will do what it takes. Do you have any suggestions?
