I have pain in left lower back, when I sit long, lift something or try strech. What can be and what to do to find out what is going on? Thank you!

LBP. Left lower back pain in 27 y is most likely muscle & ligament strain. Herniated disc, ankylosing spondylitis , and kidney stone can be the possibilities. Please see your doctor for good history and thorough physical exam and some diagnostic tests. You are already on movalis which is anti-inflammatory medication. Continue it.
