What causes weakness in the lower left side and legs?
Patient: I ve been experiencing a weakness on my lower left side, legs, after having lower left side back pain, it moved to my left leg. That s been going on for 4 days, no other symptoms. Today, I got very numb and started sweating and felt very out of it. Any ideas? Doctor: Hi i am Dr Ahmed Aly    thanks for using healthcaremagic site ,I had gone through your question and understand your concerns ..  That could be a muscular spasm or a kind of nerve compression due to heavy lifting , vigorous movements  , trauma or injury , bad sitting or sleeping postures .  These given symptoms may show some sciatica due to neurovascular inflammation which may subsides simultaneously within days or extend to chronic pain if un treated properly .  For now i may suggest advil tab when needed , hot massages with topical gels , muscle relaxants , B12 vitamin supplementation will be effective for mild cases else i recommend MRI on spine for proper evaluation and management .Please click and consider a 5 star rating with some positive feedback if the information was helpful.
