I Just Turned 50 - I Am A Male -

I just turned 50 - I am a male - 5'10" about 190 lbs and relatively healthy. I have a pain where the bottom of my right buttocks meets the top of my leg. The pain comes and goes. It almost feels like a bone bruise. In a sitting position - using my hand I can press the area and it feels like a bone where the pain persists (it does not feel like there is a lump because the left side feels exactly the same (i.e. bone-y) - the right side is just sore). It's not a constant pain - it sorta comes and goes. Right now - sitting on a hard computer chair - it hurts. Sitting on a soft couch - not so much. Sometimes I feel it when I am walking. I do not recall bumping it or sitting down on anything that would have caused a bruise. The area is not discolored - but it feels like it's deep (again - a bone maybe) and not at the surface. Any need for concern? Thanks. Craig
