<s>[INST] about 3 weeks ago i fell off a horse and landed on my right butt cheek. i had bruising in the shape of an oval  but there was a small section in that oval that got swollen and did not bruise. now that small section is still there as a large bump. what is it? and what do i do to get rid of it? [/INST] Hai.it could be muscle haematoma due to blunt injury on the buttock. U can try for cold compression, application of local pain gel.it takes its own time to resolve. U can take pain relief tabs like combination of diclofenac and seratiopeptidase, or chymoralforte,               or trypsin to reduce pain and swelling, if not resolved pls meet a surgeon to rule out the possible caise </s>
