Temporal arteritis

Morning everyone. Has anyone had any dealings with Temporal arteritis. I had surgery on my eye last year to correct double vision from 25 back to zero. I noticed recently I’ve been getting pain over my right eye and having gone to the opticians today I have discovered I have got mild double vision again. She has also referred me to my gp to check out the discomfort around my eye and the vain that runs down the side of my temple which is a bit swollen. Any info?? Thanks in advance x
