It: It sounds as though your daughter may have a skin infection with abscesses or "boils". These usually start out as tender, red areas which become hard and then eventually develop a "head" of white pus. Once this drains, the area usually heals on its own. Most of these are caused by staphylococcus aureas, a common bacteria found on the skin. Occasionally, however, the can be caused by mrsa, the antibiotic resistent kind of staph bacteria.

Next time your daughter develops one of these infections, start out by applying warm compresses to the area to help draw the infection out. Then, you should take her to her doctor so that they can drain it, test for what bacteria is causing it and be able to treat her appropriately - sometimes with antibiotics, sometimes just with drainage. If she ever develops fever, chills, or feels ill with this infection, call her doctor immediately.

You can try and prevent these infections by practicing good hygiene and using anti-bacterial soaps. Her doctor may have other suggestions for prevention. ...Read more

I got into a car accident. I have a large bruise on my leg that keeps getting bigger and had a hard lump under skin. Its been growing every day?

The bruise =bleeding: & if there is a collection of blood called hematoma, the discoloration always get bigger & many colors. The lump = a fibrosis of the clot, the body usually cleans them up. But it takes time. May get smaller & go away, or you are left with a permanent lump of undetermined size. Just be patient, there is no serious thing going to happen. It will just sit there. Ice @ first, after 3-4 days, heat. ...Read more
