<s>[INST] Hello doctors, my age is 25 & weight 80kgs.Is there any solution for me.plz tell me what type of treatment I have to take... I m having back pain after long travelling or at the time of working in straight posture for more than ½ hr.already taken x ray for my back bone doctor said gap between last joint is less it gives pain.some exercise they told but helpless... also before 2 months while playing sports i got pain in my left leg nerves near buttocks .now i cant sleep in that left side position and cant sit long time in a single posture it gives me HEAVY SHOOTING PAIN while i try to change my posture.after sometime changed my posture everything is normal. [/INST] Hi, Thanks for query, As there is reduction of space between lower vartebrae you have to consult orthopedic surgeon again as you developed Sciatica which is due to pressure on the nerves coming out between vertibrae. Go for back extension exercise,avoid forward or backward movements.use hard bed for sleeping. Ok and bye. </s>
