I've never heard of left abdominal swelling & pain with shingles. Please contact your doctor to get this checked out. I'm so sorry you're dealing with so much pain. It's absolutely awful. And the post-herpetic neuralgia doesn't help.
I had the original Shingrix vaccine in 2018. Then I had the 2 dose vaccine in the spring of 2023. One month later I got the worst case of shingles in my life (I've had it 4 times now). I'm immunocompromised, so my doctor said it probably didn't work for me (he also mentioned that it's only 98% effective). Wishing you good luck.
