On Thurs Evening While Getting Into Bed For The Night,

On Thurs evening while getting into bed for the night, I started feeling pain like a Charlie horse pain on my rt hip and had trouble just flexing my leg getting in bed. All night I could not find a comfortable position for my leg to rest but following morning it felt better. I tried to limp my way through Fri. and Sat. avoiding much weight, but Sunday morning the pain is back. I don't think is broken. maybe a pinched tendon? Im perplexed! hopefully is not too serious...
