Hi! I'm new-ish myself. You're in the right place.
I've been tested for MS on three separate occasions but am now reasonably positive my screwy symptoms are caused by a combo of Sjogren's and fibro. The problem with MS is that the symptoms can resemble many ailments, including fibromyalgia, and the onset of your symptoms can precede positive results on a test by years. So you could have just fibro, fibro and MS, or something else causing your neuropathy.
Fibromyalgia can cause some really weird sensations. I haven't experienced the vibrating feeling, but I do have lots of uncontrollable muscle twitching (which probably isn't the same thing at all).
Hope you have found a rheumatologist who will help you out. I moved recently and am searching for a new doc, not fun at all.
