Hi. I have had 3 weeks of stabbing pain every time I walk/stand for more than 2 minutes in my groin and thigh. I went to my GPS and he said muscle. It kept hurting and the EL doc said MP. I am 62 r old female, am overweight but this came on suddenly. They say it's not a clot. The Chiropractor sent me to a pain doc who gave me 2 shots...one in my hip...one in my S1. So far no help. Does MP only hurt when you walk on it? I am not in pain when I am sitting. I am so discour aged and can't work. Any help you can give me would help.
