<s>[INST] Doctor my son Aditya Saraswat is suffering severe back ache in his spine and finds difficulty in sitting straight as for the last i year he use to sit for long hours to study for preparing for his competitive exams but for the last one month he is suffering from pain in his back and shoulders and now he is unable to undertake journey by bus even for 15 Kms bus jopurney in Kolkata. My family Doctor dvised for an X_Ray (L.S.Spine (AP+LAT)) and his x_Ray report indicates L5 ias sacralised - Disc soaces are normal - Both sacro - iliac joints are normal . Please advice what treatment or exercise my son should do. [/INST] HiT hank you for your question to Chat Doctor. Sedentary lifestyle over long period of time can lead to muscular back pain. In my opinion your son is likely suffering from muscular back pain. He will need physiotherapy comprising muscle relaxation and strengthening of weak muscles. For the exact type of exercises he will need examination by a physiotherapist. Local analgesic gels and anti-inflammatory medicines like ibuprofen will also help for pain relief. Spondylolysis is a break in part of the bone of vertebra and is one of the causes of back pain in adolescents but related more to activity than sitting. Also, this is not as common as muscle related causes of pain, so it is worth trying therapy first. If the pain is increasing despite all above suggested measures consultation with orthopedic surgeon for further imaging will be required. Hope this is helpful. I would be happy to answer any questions. My best wishes for Aditya future. </s>
