I agree about getting her skin checked. I had a mole on my butt for years, it started getting hot, itchy, painful. I ignored it for over a year assuming it was just sitting on my big bum too much but my bf at the time forced me to get it looked at and just as well he did as the did a biopsy and found pre-cancer. If I had continued to ignore it for a few more months it would have turned into cancer. Anything skin related should be checked out and it is better to be safe than sorry.
