Hi there - so helpful to explore the big questions here. I am struggling with sciatica and am currently in PT for it. I have been recommended to get an MRI for a likely herniated disk but I am very skeptical, as I fit well into the category of a person likely to have TMS - all the typical frightening host of symptoms that never amount to a serious illness and tend to come and go. The sciatica is really giving me a run for my money though. My question is - since this has not become a chronic problem yet, and has "healed" before with PT, should I pursue the medical treatment for now? In other words, can a herniated disk actually cause sciatica and be worth a serious course of PT and perhaps a confirming MRI? Is it only when symptoms seem to become chronic for no medical reason that one should get on board with the TMS approach? I am fairly convinced that if I get an MRI and am told I have a herniated disk, that I run the risk of never getting better because I will become too attached to the idea of having something "wrong" with me. Thanks in advance for any thoughts. I am a psychologist and am thoroughly open to the likelihood that my mind is creating symptoms, but don't want to give up on (medical) treatment that may actually help.
