I have had just excruiating pain in my inner right thigh into groin area. It last for almost five minutes and leaves no after soreness, etc. It is so painful that it makes me nauseous and nothing relives the pain. I have to lay over the back of our sofa and just scream in agony until it subsides. My husband tried to massage the pain as in a leg cramp but that does not even help. I need to know what is causing pain. I am a healthy active 68 year old female.
