As an overweight man, I have sretchmarks on some parts of my body, including my waistline. A boil-like hard spot formed along my waistline that became tender and painful. When I tried to pop it, there was only a little puss and then some blood, but the hole was bigger than I expected and has not closed after two days. I have been putting a bandaid over it to make sure that it does not get foreign debris into it, but how concerned should I be? Should it be scabbing, or undergoing some other process to close?
