<s>[INST] 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? [/INST] Hi I am Chat Doctor. .  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.
