I believe this disease can progresses. It can have periods of time where it feels worse and times it feels like you are cured. I feel you with the pains in the back and rib cage. It can get so bad at times it feels like the time I had pneumonia. It happens often. I hate it. It can get so overwhelming at times, especially when you have followed all the right steps and taken your pain meds. Know you are not alone in this.
Best wishes your way-Nicky
