Since my back surgery in 2010 I have had chronic back pain. When my groin and inner thigh began to have pain I thought it was related to back issues and a local doc was ready to do another back surgery. I sought second opinion from Mayo and the problem was correctly diagnosed. I had THR surgery in Nov. 2021, am walking upright with no pain and no cane. This surgery even lessened my chronic back pain. I am grateful I did not go ahead with another back surgery.
