two weeks ago today, I sat on a stool to put on my makeup as I do every work day and it felt like my right butt cheek was sitting on my robe sash or something. Further inspection revealed a very dark purple bruise on my upper inner thigh the size of an orange. The bruise is virtually gone at this point, but again today my butt cheek feels like I'm sitting on a bump. Whatever it is isn't topical. Thoughts? Time to worry??
