I am very concerned about a friend of mine who has all the symptoms of GCA except her blood tests show nothing untoward. She has been to hospital twice where they have carried out scans, eye tests, etc. but nothing shows up. Her head aches are terrible, she can't eat because of pain in her jaw, her neck is agony all the time and she feels dreadful. Two weeks ago she lost sight in one eye for about ten minutes and now has blurred vision all the time. She started having symptoms about ten weeks ago. She is now having to wait two more weeks for a biopsy. Her consultant says he doesn't think it is GCA as she hasn't enough symptoms but from what I have read she seems to have most of them. What should she do as she is feeling pretty desperate? The strange thing is I had exactly the same symptoms, as did my son, starting about the same time and my GP thought I might have GCA but after suffering terribly both my son and I recovered without any treatment. Is there a virus that mimics GCA as several other friends are experiencing similar symptoms?
