My daughter was bite by a dog a month ago and she had stiches. About 4 days ago the scar by her eye has stuffed to puff up and has hard lump now. She won't let me touch it and says it hurts but she is three so I can't ask specific questions. The area is slight red color and the lump is the size of a good size mosquito bite. Should I take her to the doctor asap or ok to wait as I cannot get into her doctor until after Christmas?
