Welcome to WHL.
I am glad, that you have found us.
New or changing symptoms are quite normal, every time I think, I have had a real weird symptom, another, even weirder one appears.
I know about vibrating, buzzing feelings in the leg and foot. It can drive you crazy, but I guess it is normal, that is what my rheumy tells me.
Having low vitamin B, C, D, low potassium, low this, low that, is also normal.
Are you on any meds?
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
