Hi Dr. Rynne . . . . . . I started feeling upper left thigh pain about 3 weeks ago. I don t recall injuring it at all although I usually bike around 100 miles per week. I visited my primary care doctor 2 weeks ago and his diagnosis was a thigh muscle strain. I originally thought it might be a groin pull due to the pain being in that area. My doctor also checked for a hernia which he said I didn t have. He gave me an order for up to 12 visits for physical therapy. I ve completed 4 visits, consisting of stretching exercises and electrical pulse and heat treatments. The PT doesn t seem to be helping much and now I have the same pain in my right leg. There are days when it feels good and biking seems to help (although I haven t ridden in a week). My doctor did not take any xrays or prescribe any medication for me. I guess I m wondering if there could be another cause for the pain? Thanks! Steve
