Hi. Sorry to hear you are having this. You mentioned the last two years, but not your age. I’ve had RLS since my mid-30s and am now 69. So I can’t speak to vaccines and other environmental factors, except that they likely aren’t my cause. Then again, as kids we used to love to run behind the mosquito fogging truck and I was a decent runner, so I was up there in full fumes. We laugh about it as a stupid kid memory, but who knows what toxins I took in. Good luck with your situation.
