Hello,
It looks like a boil or an abscess. Apply hot compresses on the boil. As long as the boil is hard, it is difficult draining it. But once it becomes soft, drainage is easy. You need to consult a doctor for its drainage or for prescription of antibiotics. Take some over the counter pain reliever and consult a doctor for examination and antibiotics prescription.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Also the muscle around the bump is hard, and about an inch cirle arount it is really swollen, it looks like a messed up nipple.
After taking a shower its seemed to get worse, it swelled up with a white/clear head and then popped with a clear liquid coming out.
