Hello. I am new to Spine-Health. I am hoping someone can give input regarding a problem I am having. I am a senior, and have worked out alot in my life, but allowed myself to become a couch potato over the past winter. I was doing well, getting my muscle strength and energy back thru weights and exercise this summer. Then I saw an 'expert' on tv praising the benefits of doing lunges, an exercise I have never done. Kidding myself I was still young, I did 20 lunges. (its bad when you have no one but yourself to blame]. After that I had pain in the head of the femur where it goes into the acetabulum [hip]. There was some low back pain on that right side also for a few days, but that went away. Alittle sciatica, but mostly pain is localized in the hip. This has been a problem for three weeks now. Can anyone tell me what kinds of problems lunges can cause? Many thanks.
