I’m a 45-year-old female in reasonably good health. I’ve always been physically active playing tennis, aerobics, walking, etc. Three years ago, I was dealing with low back issues – spasms and a mild burning sensation radiating to my butt. No pain in my legs. I didn’t have pain all the time but it got triggered by sitting for more than 20 minutes, standing for more than 20 minutes, sneezing, coughing, or any other jerky movement. MRI indicated minor disc bulges in L5/S1 and L4/L5. I tried medicines, PT, injections, but nothing helped. Five months ago, a pain specialist suggested Radio frequency ablation in my low back. I did that. After that, my symptoms got amplified. I’m a bit better now but I still experience the burning sensation on the left side of my low back and sometimes it radiates to my butt. During a flare up, I feel like something is swollen there. Again, I don’t have pain all the time but it gets triggered by those things I mentioned. When the pain comes, it stays for a long time. As a result, my quality of life has been compromised greatly. Anyway, I’m 90% sure that I have TMS. My questions are: 1. My symptoms seem like nerve damage or pinched nerve or something. Could this still be TMS? 2. In addition to the MRI, should I consider other tests to rule out structural issues? 3. If yes, what tests should I consider? EMG? I want to be 100% sure that it’s TMS. Otherwise, I know my brain is going to play tricks on me. Any thoughts or advice?
