UTIs - anyone had relapse/new activity using Uromune vaccine?

Appreciate this is pretty niche, but hoping others might have tried Uromune (UTI vaccine). Within 4 days of starting I’m getting MS activity down left side - pins and needles and buzzing. Life has been pretty cruel to me but thankfully my MS has been extremely kind, it’s benign and I’ve not had activity for many years. Uromune is an immunostimulant so don’t think it’s coincidence. I need to continue as I’ve had a chronic (constant) multi drug resistant UTI for 4 years, just wanting to gauge risk. Have appointment with Neuro to discuss in a few weeks. Thank you.
