Reading WebMD, it does sound like it could be a lipoma. Appreciate you putting a potential name to it. Just weird because it's right were I sit so I'm sure that riding had something to do with it.loudog said:weird. might be a lipoma. does it ever go away? if it gets larger it may need to come out.
While it could be lipoma, I would look more toward a cyst or abcess. IOW, a pimple that is relatively deep within the skin rather than directly on the surface. These things can swell and require medical intervention, so keep a close eye on it or get it looked at.newridr said:This year I've seemed to develop a soft nodule on one of my sitbones. Sort of painful when I sit right on it (altho, because it's soft, it moves around a little bit). Anyone else experience this and what did you do about it?
