The symptoms you outlined are indeed very concerning. Without a neurological work up, it is impossible to identify if it is or is not multiple sclerosis.

So many neurological diseases have symptoms in common. The issues with your feet could be diabetes or multiple sclerosis.

Fatigue? It could be lupus or multiple sclerosis.

And all of this could be a different disease that I am unfamiliar with the symptoms.

As to your fear? You get to own that. You can either live by self diagnosis or you can attempt to get answers by going to a neurologist. Doctors are people who want to help. Some doctors are better than other doctors. Sometimes one has to go to more than one doctor and listen to what each has to say. Do not doctor shop in order to find a professional that will confirm what you want rather than practice good medicine.
