Pain in left side mid back not.sure if it.is a muscle issue cos I workout and I am undergoing.physiotherapy as.well but the pain seems to.be radiating to the lower back as well sometimes but still manages to stay on the left side only and not the centre portion of.the mid back so.I'm worried if it is again the
kidney issue as I also take supplements and workout and consume sufficient water as well kindly advice.
P.S- I have had a kidney stone in the past
