Thank you so much for your help.
@Lee, I am not a fan of MRI :} I'm scared of being in small spaces. I had one done once and..it was enough for a lifetime : )) But thanks so much for your advice. I will make sure I eat sth before taking NSAIDS.
@(JD) Thank you very much. I will try out some exercises once I can move more. I slept with a hot water bottle yesterday night and I feel better today. Still can't bend down or turn to the side..I'm starting to think I'm doing weird contortions when I'm asleep..Otherwise I can't explain why I get these backaches every now and then. I also get some backache from moving furniture or carrying heavy stuff but that is usually tolerable. A few months ago I woke up and I couldn't move at all and I ended up staying 3 days in bed. Maybe I need to move around more during the day so I stop moving during my sleep :} Again thank you for all your great advice.
