Most often, I've been having stabbing pains in the same location in my left thigh for over 25 years. I have a lot of stabbing head pain and random stabbing pain in other body parts. I'm not a doctor, so I can't say what the cause of your pain is. What I will say is that my pain was and is real. It took me many years to get to the right doctors to listen, provide answers, and help. May you do so swiftly.
