Evenity side effects? Bloating and pulled muscle sensation?

Since beginning my Evenity treatment, I have always opted to take the shots in my stomach. The first month I had a rash like reaction. Rather than quit, my doctor suggested taking a Benadryl before the shots and directly after - rash issue resolved! Every month since has been the typical, pain immediately after the injections (I have them both done at the same time - 2 nurses administer) fatigue (probably related to the benadryl) and slight discomfort for the next day or two. Yesterday was my 7th round of shots and the reaction is much different. The left side injection site feels fine, but my stomach is super bloated and the right side injection site is excruciatingly painful (and more distended than the left). The pain goes deep and feels much like a pulled muscle - moving, laughing, coughing... all exacerbate the pain. Has anyone else experienced something like this? I haven't contacted my doctor yet as I am hoping rest, some pain meds and a heating pad might help but so far not doing much. Thank you for help!
