<s>[INST] Hi I am a female 19 years old and I have been having sever back pain ranging from my lower to mid. Back. Occasionally it extends all the way up to my next. The pain tends to become the worst at night. I have trouble falling asleep and getting comfortable without being in pain. It can take me sometimes 2 hours. It also hurts when I sit for too long. I have been taking aspirin using heat and stretching to try and relieve the pain but nothing seems to help. I was wonder what some suggestions maybe for me, if you may know what it could possibly be based on these symptoms or if the is a specialist I should go see. [/INST] Hi if you do not have regular fever, no pain in your limbs, no localized pain at back then my suggestion would be following for 3 weeks, then come back to me- 1.improve your posture by sitting straight, walk straight to simplify behave like a soldier. Avoid constant sitting that is not more than 30-45 min. 2.take diet rich in calcium and it. D like milk or milk product.  3.regular back strengthening exercises.  Wish you good health. Take care. </s>
