I did not have muscle pain but developed severe insomnia a week after my injection...it was the worst I'd ever had in my life. I thought it was maybe just a menopause thing at first, but decided to not get another injection. It stopped a week or two after i stopped the Evenity. I was told no one else ever had that side effect, even when i called the drug company to report it....this has to be a lie as I've found it listed as a side effect on drug information sites. Even my pharmacist found it listed. I also developed horrible pain in my teeth, extreme sensitivity that also went away when i stopped the drug. I've yet to find a bone drug i can tolerate. These "one size fits all" approaches for women's health are total BS. Someone who is thin, short and 100lb is not going to need the same amount of medication as someone 200lb, big boned, tall, whatever..different body fat percentages, different muscle mass, different hormone levels in the body. They just don't bother to do the trials for women at different sizes.
