Shingrix - Shingles/Shingrex Vaccine?

I've been on a maintenance dose of valacyclovir 1 gram tablet, per day for the last 3 months. I've had shingles 7 times this year. I was finally feeling much better after addressing other health issues. I discussed with my doctor getting the vaccine. She warned me that it could cause a flare, but she thought we should move forward. That was exactly 2 weeks ago.

My arm at the injection site ached for about 5 days. However, 2 days in, I started getting the itchy sparks on the backs of my legs. I ended up with the worse case of shingles I've ever had. It was on the back of both legs. My right leg was ankle to upper thigh. My left leg was calf and the backside of my knee. I also had a small spot on my right arm. I've never had such a horrible rash and on both sides of my body. I immediately upped the valacyclovir to 3-a-day, per doctor's orders (previously discussed and ready at first signs).

I am on the downside of everything now, but I have no idea how long the rash will leave marks. I also cannot bare to think about taking a second dose. It seems to me that would just be insanity.

I don't know if any of this is helpful, but this is an honest account of my experience over the last 2 weeks.
