<s>[INST] I was lifting a chair out of the back of my truck and had my lower back make this popping sensation I felt pop about 2 or 3 times. I am in a pretty good amount of pain now with not being ableto bend forward much at all or lean to the side. Also not able to lift or pickup anything [/INST] HiThank you for asking HCMI have gone through your query.In your condition an intervertebral disc bulge of lumbosacral spine or a strain/sprain can be suspected.A physical examination with an orthopedician can give clue for that and a X ray followed by MRI if required can confirm it.For such cases in my patients i advise NSAIDs like Aceclofenac muscle relaxants like thiocolchicoside and neurotropic drugs.I also advise them to have a rest of 4 to 5 days.I send them for physiotherapy along with this.Lumbar supporting belt also will be helpful for some.Hope this may help you.Let me know if you have any further query. </s>
