question: 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
