have cellulitis still...

on my arms contracted from itching my poison ivy and rinsing dirty old bottles dug up from old dump sites,for money,from selling them. Dipped arms in dirty water and toxins,bacteria,staph,got into my body,ery serious,swelled,painful. Am taking antibiotics for it so better but still there as itchy and scratch and gets red again,swells. Just need to give it time. had made a poultice of apple cidar vinegar and hot water and dipped gauze in it an applied to wounds but may have been too strong and burned it.
