I already had idiopathic peripheral neuropathy when I contracted shingles in October 2020. I was weakened by cancer radiation and chemotherapy treatments I was having. My shingles was in my left arm, and the pain in the nerves from neck to wrist in that arm stayed 6 months, over the normal PN pain and tingling in that arm.
As soon as allowed, I got the 2 Shingrex vaccines, having to carefully time around getting the Covid vaccines as well. All I can say is that the vaccines, for me, were nothing compared to how I suffered with getting Shingles!
My regret is that I didn’t get the shots at age 50, before I ever developed Neuropathy or the dreaded Shingles. But when I was 50 the vaccine mostly used was for 60 yr olds, and with Shingrex they said it was for 50 years old, but I fell through the cracks and didn’t get the memo….. everyone is different though, listen to a doctor you trust.
