I have what feels like a lump in my right buttock. Sitting is very painful. Feels like hip bone is going through flesh.?

Stretching helps. Avoid sitting with wallet in back pocket. May be a very tight muscle or pinched nerve. Stretching helps. Sometimes a heel lift is required. A low back adjustment may be necessary as well. If not relief with this or anti inflammatory medications, further testing, such as an x-ray, ct or MRI may be needed.
