CAT BITE

okay so the other night my cat was laying on my chest and he was kind of biting my thumb not hard tho and he bit really hard on acident and i think he hit a nerve cuz i felt it in my whole arm xD after that he got mad cuz he stopped chewing my finger and he lays on my legs facing away from me flicking his tail xT hes such a baby i cant deal with him sometimes xD but now i think the bite is infected sooo yk but ive had wounds infected before and didnt have to go to the doctor or anything so i think ill be fine??
