I have had a cataract operation and can now see to post . Something that has been bothering me is a link that was posted awhile ago about GCA being linked to the Shingles virus. I have had GCA since 2012 and recently ( last June) came down with shingles. At the time someone else posted that her symptoms were helped by the anti viral given for shingles. I concurred. PMR pro thought that it might be that the brain could only deal with one pain at a time...( there was a name for the theory). Anyway...the study said there was compelling evidence that the onset in the elderly was linked to the varicella zoster virus. My question ....why can't we take the anti viral medicine ? I still have nerve pain connected to the shingles and sometimes have a hard time differentiating the pain . Just a thought.
