So I am fairly certain my pain is 100% TMS, but I am still experiencing doubt and fear that there is something structurally wrong with my left leg (where I have had majority of my pain for 12 years.) It is mostly sciatica type pain and pirifornis stuff but also hip pain, knee pain/clicking, limited mobility, nerve damage type stuff. All on left side. Here is my question/concern: when I sit cross legged and bend forward, I can actually feel my piriformis muscle (or something) rub on my sciatic nerve and can feel the nervy twinge happen all the way down to the foot. This happens every single time, whether I assume/expect it will or not, and only on left side, i.e, my fear something is structurally wrong. I can feel the muscle irritate and "move" the nerve in my left buttock and radiate! I'm not imagining this. I don't know how else to articulate it... Is it possible that my horribly stubborn TMS had produced actual physiological changes in my left buttock and leg and that is why there is a structural feeling problem? (I don't know what I would do if there were ACTUAL structural issues - I highly doubt surgery of piriformis and or sciatic nerve would change anything... Maybe it would? Do people even get surgery there?) I have had my pain and symptoms (sometimes more feeling of left leg being "off" compared to right, numb, heavy, tingly nerve symptoms, weak, not always pain) since I was 18 years old, and it has been so hard to accept there is no structural damage. I had an MRI of my low back and hamstring done (where I had an initial injury) and everything is normal in those areas. Should I get an MRI of my buttock now? I know I sound a bit crazy. Please try to be understanding. I exasperate myself, trust me! I have every reason to believe I have TMS, but the structural feeling stuff with the nerve/buttock is really throwing me. I have a hard time understanding if TMS produces actual physiological changes vs. the feeling of physiological changes. So for example, could TMS process be literally inflaming the piriformis muscle chronically (because my various symptoms have always been chronic/constant) and then causing this sciatic nerve rubbing sensation? I hope I am making sense. Also, is my assumption that my body should go back to the way it was before this pain ever started expecting too much and simply accept diminished symptoms? I think I believe my left side has been damaged by years of this TMS process. I appreciate anyone's thoughts and feedback. I promise I am open, even if I sound like I'm not! Thank you!
