I'm worried I have MS: Can anyone give me advice?

I have been sick off and on for the last 8 years. 
I have Multiple leasions on my brain. I go through periods of time where I am so tired I am taking a 4 hour naps then I may go for months and feel fine. My legs are heavy at this time and I have also noticed that the front of my shoes are scuffed up. (Family and friends have brought to my attention it’s because of how I walk sometimes) went to the er because I was feeling an electric shock in my body they look at me like I have two heads! Then come in and say they have only heard of that in ms patients. Please help on what to do. 
thank you

tired and hurting and scarred
