[|Human|] Umm hey. I have lower back pains like near my butt crack sorry for the language and I have like a bump. It s hard shaped like an oval. Not a spider bite or insect bite. But it hurts to walk to stand sitting down is almost impossible I can t put any pressure on it. Even when I lay on my stomach it hurts. And I have no idea what this bump could be. I didn t fall of anything so I have no clue.. Please help
[|AI|]  Hard swelling over lower back or sacral area with severe pain that get aggravated by even slight touch and movement is suggestive of some infection. Most commonly its infection of hair follicles. That we call folliculitis. This can be managed by topical application of some antibiotics ointment and if severe you may need to take oral antibiotics. If it is not subsiding you should consult a dermatologist.
