"Trust me, as a nurse of 40+ years, it was not blepharitis. Now both eyes are sore and painful."

Are your eyes sensitive to light? Do you see floaters? Is your vision getting foggy?

I had uveitis. My symptoms progressed rapidly in a matter of a day or two until I couldn't see with one eye. Uveitis can affect both eyes at once. My uveitis had an acute onset but there is a chronic type of uveitis. too.

Uveitis is associated with inflammatory arthritis more than PMR. I think uveitis can happen with any inflammatory disorder when our immune system becomes deranged. You can also have more than one inflammatory disorder.
