I am online because my significant other is always working with his hands, yesterday he was outside tinkering with a lawn mower I am now really concerned because he cut him self and rust is a factor, his finger is now swollen badly around the nail, he has no health insurance and he is very reluctant to go to the doctor, what should we do, we have antibiotics but are not sure what we can do, i do know if there is any red lines it could be blood poisoning help, what should we do?
