Hello everyone. I am new to this; and the reason why I registered was to see if anyone out there can help me with my frustrating injury-no diagnosis! Here's my situation: For the past 2years now I've had this nagging pain on my left hamstring that shoots to the inner thigh, up the groin, and up to the abdominal area. Every time I try running the pain happens. If I walk fast it hurts! I've had an ultrasound to rule out a sports hernia, I've had around five Wikipedia reference-linkMRI's and countless x-rays. No one can find a diagnosis. I've tried accupuncture, physical therapy and seeing a chiropracter. Nothing has helped!!! Can anyone provide me with some feedback??? Thanks.
