So, 3 months ago, I felt down the stairs and got an enormous bruise on my left butt cheek. It hurt pretty bad and it took around 3 weeks for it to completely disappear; however, I started feeling a bump (that hurt) where the bruise was. I looked on the internet and found out it had the symptoms of a Hematoma. I didn't paid much attention to it, because I thought that it would go away with time... 3 months have passed and it still hurts when I touch it and I don't know if this is normal. Should I go see someone? Or which things could I try first?
