In regards to MS, it honestly doesn't sound suggestive or consistent with a neurological condition like MS, what you describe is in all peripheral limbs, in both upper and lower (fingers, hands and toes, feet) and your symptoms have multiplied rapidly over a few months from the initial issue (face droop), which all the types of red flags that point away from MS and not towards it.
I think you might need more support from your general physician than your getting, a lot of symptoms can be treated prior to an official diagnoses of something so it might be beneficial to see your dr and ask for help whilst your waiting for your neurological appointment...
I hope that helps....JJ
