im new here and have a problem that is very painful and irritating, but dont know what it is. my MRI results have showed quite a few problems with my lower back but nothing in my thoracic area. my back we will say goes out, basically seems like the air is being knocked out of me and makes me nauseus and doubles me over in pain. the pain does not subside until i have someone step on my back and it pops. after it pops im fine. it happens 3-4 times a week never during any particular activity. ive gone to chiropractors and pt neither have helped any. i guess im looking for anyone that has similar issues or any advice.
