A few weeks ago my back started spasming. I went to my mums chiropractor but they didn't seem to help much. Gradually it started to improve until today when I sneezed in the shower and omg the pain is unbearable. I can barely move. I have taken ibuprofen and its not helped at all. What could be causing all this pain (I haven't done anything specific to cause the pain in the first place) and what can I do to help it?
