I Develop An Ache In My Right Hip, Deep In.

I develop an ache in my right hip, deep in. After a few days soreness migrates to the side of butt and becomes an open soar, like a cyst, it drains very little and goes away after about one week. this reoccurs about two or three months a part. over the past three or so years. I am 62, I take no meds at all, active in work and play.
any ideas or need more info, YYYY@YYYY
thanks for all of your time,,
