Hi welcome to hcm
I understand your query and concern.
Burning pain in the back could be related to pathology in the spine which should be treated in multimodal approach which can be probably suggestive
disc prolapse.I advise you to get an MRI spine,complete blood picture,ESR,Urine culture immediately to confirm the diagnosis.I also advise you to get an ECG,2D Echo as a part of routine screening of your heart.In resistant cases you may also need to get
lumbar puncture and CSF analysis for exact etiology. You may need to get an chest x ray and AFB for sputum analysis to look for any tubercular foci.You may need to use course of antibiotics like Cephalosporins,Analgesics,NSAID's immediately by consulting your doctor.You may also need to use
Pregabalin twice daily for 3 months by consulting your neurosurgeon. Avoid excess strain.You can practice Yoga and
Physiotherapy by consulting your Physiotherapist.Diet rich in fruits,dates,Vegetable salads,dry fruits,proteins are helpful in your case.
Bed rest for 3 months will be helpful.Water bed for sleeping with cushions is helpful.If still symptoms persist you may need surgical approach.Consult your surgeon for expert management.
Post your further queries if any,
Thank you
