Mine seems to increase throughout the day. It's been 6 days since my last injection and out of those days only 1 without burning sensation between my shoulder blades. I was going to stop after 7 but went one more at my doctor's urging but this is no kind of life. It's hard to do much of anything. Every activity (besides sleeping) seems to irritate my back. I'm thinking of getting ahold of my doctor and calling it quits on Evenity. Hoping that 8 months has had some positive effect. Sorry you're in such pain. I can empathize.
