I have been coming to this group for almost 4 years and have never heard of a connection between MRI's and Grovers. Shingles shots, my situation, yes, but not MRI's. If it is Grovers, you will not get rid of it, only control it. There is no magic bullet, different things work for different people. Seemingly, the most effective way to mitigate the itching is Cilantro, either in leaf form, in smoothies, or the tincture, available on Amazon. Despite running in cold temperatures, your body still sweats, which does prompt itching. I suggest that you read a number of the past blogs. There is more information there than any derm can give you. No question, GD is a drag, and there is no cure. Just keep reading this blog for other peoples experiences and advice.
