My lower spine hurts a lot when doing work or resting. However I twist my back so it clicks it eases the pain for a while then returns with stronger?

See a physician. As soon as you can. At 25, you should not have so much back pain. Ask your physician about akylosing spondylitis. You are a male in mid 20's, which fits the onset and gender for this diagnosis. It may juts be something basic back issues or a congenital spondylolsis, but you really should have an x ray of your spine and find out also if you are hla b27 related.
