I am a 57 year old woman who goes through periods of being very active and then not so active. I have had hip pain at night off and on for the past several years. I get it whether i exercise or not. My pain does not radiate in my legs or back. The best way to describe it is a severe ache that feels like I have been sleeping on a cold wet ground (if you've tent camped you know what I am talking about). I do release exercises and I sleep with a pillow between my knees but still get no relief. It does not bother me during the day but oh boy, I nights are dreadful.
