We use a lot of misnomers at times. Trapped? Pinched? The words don't really mean anything. The problem could be any number of things including what is in reality disc material being compressed to one side or the other and applying pressure to a nerve. This problem can be as serious as a hernaited disc or a degenerated disc due to an arthritic condition. I fought the problem in my lower back for years and tried everything including acupunture. Eventually I had a laminectomy which fixed the problem....that was 15 years ago.Don't know what to tell you right now ..... but you need to see an Orthopedist before you get involved in all the wacko remedies so you know exactly what the problem is.
