A friend shot meth into his hand yesterday & the swelling HASN'T subsided but has gotten WORSE, extending now down his wrist. When i seen it yesterday I looked it up and said it could of been into the wrong type of vein, ice it the first 24 hours & 90% of the swelling should be alleviated. I don't know if I can convince him to go to the hospital but what would cause that and should he seek medical attention?
