Getting a lot of thoracic pain including around ribs after 1st Evenity shot. Seems to be reducing now after about 10 days. Like you I thought I had fractured Rheumatologist has examined me and thinks its unlikely but awaiting a scan. Never the less what he did say is that whole thoracic area is very stiff - muscles do feel very tense and on occasion go into spasm. However now I am aware that pain is mostly due to stiffness I seem to feel more relaxed and pain has lessened and is more manageable. I think because this is such a new drug and I am aware that side effects can be challenging my mind went into overdrive. Feel more positive and willing to keep going with it - at least for the time being.
