Seems there has been a few people on here questioning the tdap----my neuropathy started several months after a tdap vaccine, but I have never had a Dr. have even the slightest interest in the connection.
Mine is believed to be acquired/immune related and shows up clearly on the emg/ncv.
I don't think being tall causes neuropathy in any way, but it makes sense that being tall would mean the nerves are longer would require more healing time. I am tall as well (5'9")
