Prednisone zone fog or GCA

[Plains]

For several months I have been reducing my prednisone by 1/2 of a mg. I am down to 4mg. 3 mg in the morning and one mg around 6pm. My head feel tight all over. I did have a very stiff neck and ear pain the last time I was at 4mg. They check my sed rate and C reactive protein… both were high. Went up to 10 mg, everything went away. As I said I have been slowly tapering to where I am today. No real neck pain or ear pain, my head just does not feel right. I have no real pains anywhere else. I read about GCA and I don’t seem to totally fit the symptoms. My GP has ordered an MRI to to make sure nothing else is going on. He also did some blood tests again to see where I am. Can my head stuff be from reducing the prednisone? I forgot to mention once in a while a get sharp pains in my head. Mostly it the front of the head like a hangover head feeling without drinking! Lol

Have a good day everyone, as always thank you for your help!
