The prednisone absolutely worked for the internal vibrations. And other symptoms. Why I can’t tell you. Some sort of inflammation we may have. I got the booster and this is when all the symptoms began again and I regret getting it again thinking the antibodies would help. Now we are all different but I’m never getting it again at this juncture. When it makes one worse not better or did I wait too long so many questions it’s not worth it. I heard gaba has helped. Dr’s are hesitant about prescribing prednisone but a couple medrol packs should be able to let you know whether it would work and being persistent about it should help. GABA has a lot of side effects as well so low dose of either or is a double edged sword bc god knows how many mg’s of gaba they are going to have you taking a day.
