[/INST] Dear patient Your back pain and sex affair seems unrelated.  Back pain is related to your work and the odd positions in which you work.  There is word ergonomics which is science of work and positions. Best position for computer is when you sit in chair with your knee joint and hip joint are at 90 degree with back supported and foot on the floor. Your eyes should be facing straight into computer screen. Try this at your work and you will benefit in long term. Meanwhile, continue your medications. All the best. </s>
