I may not be the best in the advice business but I am 72 years old and have suffered chronic pain for 45 years. I have had 4 spinal surgeries including 3 fusions. I have had physical therapy off and on over the years without much success. Fortunately, it sounds like your problems are not at that level. I can tell you that I finally found a physical therapist that has made a difference in my comfort level.
He is my age and still helping people. My neighbor, a uroligtst, was suffering back pain and I suggested he see him. In 2 visits he had him back doing surgeries. I think mostly he was suffering from back strain and over doing it. The Big difference for me was his use of dry needling. He also works me over applying deep muscle massage. I would say don't give up on finding someone who can really help you get back where you can enjoy your life. You have to take charge and become the expert on what works. Good luck
