Thanks so much for this information. I have been treated for PMR for five years. Tapering doses of prednisone up and down, multiple flare ups. I was down to 2mg, having pain but able to manage with the help of acetaminophen. Stress seems to aggravate it, so during the holidays and extreme cold recently was not surprised that I hurt more. I started getting dull headaches in my right, then left temple, along with stiff and painful jaw, new right neck pain and horrible shoulder and neck stiffness and pain. I never get headaches, several new symptoms for me. Called rheumatologist who told me to come in for a steroid injection. I did, but his nurse gave me the shot and I never saw my doctor. I went on an overnight trip the next day and the following morning woke with slightly blurred vision. Headaches continued. I ended up in the ER, and was diagnosed with temporal arteritis based on symptoms, elevated sed rate and negative for bleed head CT. Gave me 60mg oral prednisone and a script for 60 mg daily in 3 - 20mg doses. F/U with rheumatologist next week. My mom had this, but not PMR. Vision is good today after 1 dose, as are the headaches. Bracing myself for the side effects.
