Two of my elderly relatives got shingles - one told me it isn’t just extremely painful skin lesions, it can be internal as well, she said her bones and joints ached with every outbreak. She said she couldn’t get comfortable and was miserable every time it recurred.
My neighbor said shingles affected his heart - he thought he was having a heart attack b/c of the pain - but all tests produced normal results. Doctor said it was a result of shingles.
Still, I’m very hesitant about taking the vaccine and so far haven’t done so.
Being unable to sleep is a huge health problem. If you do get shingles, I strongly recommend immediate antivirus.
