My sympathies
Just a reminder the Shingles vaccine- zostavax is free for those aged 70-79 on the immunisation schedule.
And if you do feel like you have it- don't delay- anti- virals are technically only PBS supported for within 72hrs of onset of rash. They reduce infectivity and post infection pain. Any rash with blisters and pain would be suspicious for shingles. Usually you notice the pain/burning first.
Get well soon!
