Evenity and tendon issues

My achilles tendons now have some pain in them and it's two werks into my first injection.

Did you experience a partial or full tear? How long have you been taking it?

I did Evenity for 11 months ending February 2023. Never had an ache or pain prior. Suffered from debilitating
Muscles aches, joint pain, feeling “brittle” after about 6-7 mos of Evenity. Took a two month break and started to feel better then started Fosomax and all discomfort came back. Switched to monthly Actonel and it wasn’t as bad so have been on that since so as not to lose gains and bone density if holding. However, I have had a full thickness tear in one shoulder repaired with surgery, other shoulder has partial tear now and I have intrasubstance tears in bicep as well. Both biceps are uncomfortable and repaired shoulder sometimes feel achy and don’t have mri of that bicep so don’t know. Knees can be tender as well which I never had. I do shoulder strengthening, overall strengthening regularly, walk and bike and do all the recommended osteoporosis supplements but feels like something changed in my body since these meds. Idk. Don’t know if that helps you but sometimes my tendons and muscles feel “brittle” is the only way I can describe it.

Thank you for your information.
My achilles tendons are hurting two weeks into Evenity.
