I Am 28yrs Of Age, 2 Years Of Marriage And

I am 28yrs of age, 2 years of marriage and have no children. height is 150cm and weight is 64.5kg. I am suffering from lower back pain, shoulder and neck muscles. have been seeing a physio therapist since November 2016 and she says I have inflamed muscles caused by improper posture at work. I'm a Chef and my working surfaces were too high for my height. that has been rectified but I still suffer from back pain. I was 68.9kg when I started my therapy and have been on a low carb diet. I go for sessions twice a week, massaged and put on tens machine and hot packs but the pain is still there. I feel tight and my shoulders are heavy, my neck is tight and lower back twitches when I walk such that I limb. what should I do?
