I already had severe idiopathic neuropathy before I was diagnosed with cancer and was undergoing treatment. While down and out, I got shingles. The Lord was testing my strength, Shingles was terrible. As soon as I was allowed, I got the 2 Shingrex shots, which were filled with 2 Covid vaccines in between as my time in line for those came up and were also priority for my cancer situation. Anyway, for me, it seems my reactions to all 4 of those (plus a later Covid booster and flu shot) were “normal” . My neuropathy didn’t change, it continued to offer its unpredictable variability day to day. But I did get mental relief of being able to better fight or avoid Covid and repeat Shingles (and flu). But, we’re all different.
