Hello, I Am Experiencing Some Regular Pain In The Morning

Hello,

I am experiencing some regular pain in the morning on the left side, of the back of area between the top of my hip and the left sacrailium joint(spelling?).
It is alarge area, about 6 inches in diameter and makes me limp. It causes me to limp for awhile. It reduces in area during the day. Your thoughts. It seem to be worse, if I have had a couple glasses of wine the night before.
