I went and popped it and blood came out it filled up a few times with blood and the pain has stopwd. I noticed it looked like clotted blood came out. [/INST] Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint a fluid filled lump in groin area over the butt cheek seems to be an abscess or a boil. It can also be Hair follicle infection causing Folliculitis. I would suggest you to consult a General Surgeon and get evaluated, and he can advise you Oral antibiotics like Sulfamethoxazole and Trimethoprim, anti-inflammatory painkiller like Ibuprofen and topical application of Triple Antibiotic Ointment and steroid ointment. Hope this information helps. Thanks and regards. Chat Doctor.  </s>
