I'm 4 weeks post brachytherapy now and about 10 weeks or so post surgery. Back is a killer all the time? Starting to worry although when I poke and prod it as you do lol? I can feel it's the muscle is tender, it's not agony just there anytime I've maybe been cleaning or stressed I guess. I sit down in work for long periods and wonder if that's making the whole thing worse. Any experience to reassure my paranoid brain.
