<s>[INST] So I first got this puss bump on the back of my left thigh. i didnt give much attention to it until it started to hurt really bad when i would sit down. when i get up, i would have this pain going through my whole leg. i then checked it again, and it was like a black dot, in puss, in a red bump. My mom & I thought it was a spider bite. So i put cortizone on it and it opened up. puss & blood kept oozing out. I would squeeze as much out as i can and clean it with hydrogen peroxide then put neosporian and a band aid on it. I continued those steps for the next few days and it went away. now its like like a black scab with dry skin around it but it doesnt hurt. then a few days later, i found another bump in the back of my right thigh, and like 4 bumps on my butt. it really hurts to walk and sit. Even move. 1 of them, i did the steps on now its just like an open cut. but another ones a really big bump and A LOT of blood and puss is oozing out. but the other 2 or 3 is still closed. Theyre ALL really painful. Im not sure if theyre bites or because of bacteria or what. Please help me figure out whats going on & ways to heal them up ! Please! [/INST] Hello, I had gone through your query and understand your concern. Short answer: Seems like fur uncles, need to take antibiotics. Detailed answer: Thanks for asking on Chat Doctor. Based on your description I'm suspecting it to be fur uncles. They are known occur repeatedly. Do not apply cortisone on it. But you can wash it with HY Chat Doctor.  Remove the pus. The problem is pus is collected within many local. Even if you press it hard it is difficult to remove pus completely. Kindly visit a general surgeon who can remove the pus by breaking those local using forceps. Also, you need to be put on a course of Antibiotics. Hope this helps. If you have any other query, feel free to ask. </s>
