3 years ago my sister had appendicitis, during the surgery, the hospital gave her a very rare infection, I think they had to call the cdc in and everything. To treat the infection they had to give her a picc line, she s all better now, but the scar from the picc line is still raised and itches very badly. I m worried it might be something else weird the hospital gave her, is there a reason it s still puffy and itchy after 3 years?
