Hi @mild835, jaw pain and pain in the temples can be symptoms of Giant Cell Arteritis which about 30% of those with PMR develop. A higher dosage of Prednisone (usually 40 - 50 mg) is needed to control GCA. If your jaw and temple pain continue, you may need a temporal artery biopsy to rule out GCA. Other symptoms can include a tender scalp, difficulty seeing, and a dry cough. I also had an incredibly stiff neck. It's best to be vigilant, as untreated, GCA can result in blindness and stroke. Wishing you the best, Teri
