<s>[INST] hi, I am 19 years of age and i  have lower back pain( muscle spasms), I went to the doctor and what i got was a voltaren injection and some analgesics. My question is what can i do to fully recover (rest, workout, etc...)?  Also, my xrays were normal but am overweight. [/INST] Hello, see these kind of backapains are due to stress indcued like wrong position, standing and  sitting in same position for prolonged period, which puts more pressure  on your lower back, endup with backache. So for that you need to reduce stress, and some workouts. Swimming is best for backache without any known pathology for backache next cycling like movements while sleeping. And dont use soft beds. Ofcorse you have to reduce your weight, that is one of the reason for backpain. </s>
