Hi, I just had my second Shingrix shot yesterday. My arm is terribly sore but so far no numbing and or nerve pain as with the first one. I mentioned to the Pharmacist where I got the first shot that my left hand (got the first and second one in left arm) in particular, the fingers felt like they were numbing. The Pharmacist told me yesterday that whoever administered the first dose may have nicked a nerve when administering the first shot. She was concerned to hear this and I assured her that it did pass in several days and I had no other after effects since that first week. She did mention that a lot of people have more side effects with this shot and that the first shot is a slightly different blend than the second one. Shingrix is a strong shot, both first and second....I believe she said it was a "live virus" as opposed to the original Shingles Shot which was not a live virus.. I hope that your symptoms/side effects pass which I believe they will. If they don't clear up, get in touch with the person who administered it and you can also call the manufacturer of the vaccination and mention this to them. Good luck....By the way, I still feel better having gotten both the shots and now I am done with it and should not have to worry about Shingles and it was worth the side effects.
