I am a 44 yr old woman and i have right side groin pain. I have been exercising for about 8 weeks now. I didn't hear anything pop, it wasn't a sudden pain. It just came on gradually. Now, it hurts when I lift my right leg, I have to use my hands to lift my leg to put my sock on. And let me tell you, it HURTS real BAD when i go to get into the car. My doctor sent me for a sonagram, it showed that my lymph nodes were swollen in my groin. Doc put me on 10days of antibiotics, now i just don't think swollen lymphs nodes could cause that much pain. I am taking advil and vicodine for the pain. Now i will also tell you that I have a history of thyroid cancer, I am a little nervous. What do you think i could be?
