@donbarkman I am trying to manage my back issue while dealing with CRC and a very sensitive gut….i use Tylenol when really necessary and have actually gotten help with back problem from the combo of a terrific PT at NYPresbyterian and an osteopath.MD (manual work )…once my core got stronger (it was weak after open abdominal surgery) I felt progress at last…just don’t overdo the exercise, rest your body or even use heat if needed…it takes patience for sure ! Just gently sucking in my abdomen, but not too far, made a difference- then I learned to breathe normally while doing that and eventually some well-chosen exercises…professional guidance can make a real difference !
