Hi @jabrown0407, before I was diagnosed with PMR/GCA my blood work showed anemia - so my PCP was wanting me to get a colonoscopy, a pelvic ultrasound, etc. Luckily, a good friend, an infectious disease doctor, took an interest, because I also had a mild case of Shingles, even after having the Shingrex vaccine. He reviewed my lab work, suspected PMR and GCA, and told me what blood tests to ask my PCP to order. When I had the anemia, I was very tired and could barely get through a long walk. Good luck, I hope you can find some relief.
