@romeo2020 Welcome to Connect. I presume your EEG was a sleep study of your brain waves? What did they image with an MRI? Did they do brain and full spine imaging? Did they check for inflammatory diseases that affect nerves and muscles like MS, etc? Am I correct in assuming that you are a guy with a user name like Romeo? So many of your symptoms could be anxiety related, or even something like Lyme disease or an exposure to something toxic like toxic black mold. With that in mind, have there been any roof or water leaks in your home? If you leave home and stay at a hotel, do you have the same symptoms? Have you considered gluten issues? That can produce gas and bloating and it's easy to test. You can also try for a week to avoid all grains, bread, pasta, etc and see if that changes anything. Have you had surgeries? Do you have any surgical implants or foreign materials in your body? I ask that because surgery creates scar tissue which can entrap nerves. Was your thyroid function normal? Too high levels of thyroid hormones cause symptoms very much like anxiety. Have there been traumatic events in your life that could be triggering PTSD with a thought or memory? You may want to write down your symptoms and what you were thinking about at the time it happened in case that will reveal any clues. If mainstream medicine doesn't find answers, you may want to consider an environmental allergy medicine physician or functional medicine. there is a provider search at https://www.aaemonline.org/find.php . Personally, my environmental medicine doctor has helped me a lot. You will also find educational information at the practice that pioneered this field of medicine at https://www.ehcd.com/. It is good to be asking questions like this of your doctors instead of waiting for them to think of something. You may get an explanation, or a response that they could look at your suggestion.

One thing I could suggest even if they don't know what causes the physical problems is to try myofascial release with a physical therapist. I have done this for several years and it removes the tightness and fascial restrictions in the muscles and allows the body to get back into better alignment. It also allows the tissues to be re-hydrated and release waste products that are stored there. It may be able to address the GI issues if your intestines have adhesions or restrictions in their movements. Have you done the normal GI screenings like a colonoscopy? If anything here rings some bells, discuss that with your neurologist.
