Ive been completely fine then suddenly i went for a shower i felt a slight sharp pain in my lower back area above my hip, i started gently trying stretches but it kept getting worse until my back locked up and now i cant move,when i bend forward its completely fine but when i try straightening my back i feel a really sharp pain, its been like this for about an hour and a half i tried slowly walking and putting a heat pad on my lower back, nothing is happening i saw on youtube something about a muscle spasm or “throwing out your back”, anyone have any advice?
