I am a person that rarely gets headaches, so I was quite surprised when the headaches came on and lasted all day long I started taking maximum doses of extra strength, rapid release Tylenol, which did nothing. First Step was to my general practitioner. He gave me some migraine medicine that did not help. He then referred me to a rheumatologist who diagnosed me with GCA. . I did not have a biopsy or an ultrasound. But did have a brain CT scan. Dr. took one look at me saw that my temporal arteries were swollen. I had jaw pain & scalp pain, I was very fortunate that my vision was not affected, Doctor said “I know what is wrong with you” he put me on prednisone and within three days the headaches stopped. They have never returned. I had to continue on the prednisone for the polymyalgia pain . However I was on prednisone for eight months and was able to get down to 0 mg by June 2024 with no help from Actemra. The headaches have never returned🙏
