<s>[INST] Hello DR. my name is jeyanthan.i m s/w Engineer. for the past 4 days i m suffering from severe backpain.normally when i m in the bed or walking or standing i never feel pain..i feel pain on my back when i m sitting  in the chair.i used Valeni spray but it s not recovered.Also when i was suffering from cold and fever i feel the backpain.i suggested some doctors here they told me that is because of fever.but now i m getting back pain when i m sitting in chair.May i know the reason or give some suggestion pls. [/INST] HiThank you for asking HCM I have gone through your query.A thorough physical examination by an orthopedician is necessary to rule out your reason of back ache.It can be due to osteochondrosis or sacroiliac joint dysfunction or arthritis or an intervertebral disc herniation.A X ray Lumbosacral spine and a MRI if necessary should be taken to confirm it.For my patients with such condition i treat with short course of NSAIDs like Aceclofenac muscle relaxants like thiocolchicoside and neurotropic drugs.I also send them for physiotherapy and muscle strengthening exercise along with these.Local injection of corticosteroids is also done in some.Wearing Lumbar supporting belts also helps in some.Hope this may help you.Let me know if you have any further query. </s>
