<s>[INST] 2 weeks ago I started having lower back pain just comes out of no where it hurt to move while I was having the pain but now its stronger pain and consistent it hurts bad an makes me fill like i gotta sick an making my stomach cramp an today I started having lose stools an blood in the stools It s like moving down into my legs [/INST] For severe lower back pain you can take some painkiller like ultracet-plus or zerodol-sp only when the pain is worse enough or disturbing your daily routine along with some calcium supplements like shackled or toscal-gem once daily. Take some multivitamin like spray or neurobian-plus once daily. Do some physiotherapy exercises after an expert opinion of physiotherapist. I will also advise you to sleep on a plain surface. </s>
