Multiple sclerosis advice

It’s got bad now and don’t work anymore. I’m not convinced it’s fibro and I’m starting to wonder if it’s ms.
Had a mri head scan done Thursday last week so waiting on results as I believe if I have ms it will show? 

You know when somethings really wrong with you and don’t think their diagnosis can be right because of how you feel? I have been feeling that for a while.

I am extremely fatigued. If I do something like I mowed grass, medium garden, been in bed 3 days exhausted and unable to do much at all. Trapped nerve feeling in my hip, bum cheek area for over 6 weeks with no reason why, making it hard to walk. Weak hands, tingling in fingers and feet, vision got worse, unexplained sharp pains over body. Memory is shocking, can’t remember why I walk in room half of time. 

I don’t have spasms though. 

In a way I’m hoping the mri shows ms so that I get an answer to all this. Especially now I’m not far off house bound.

any advice from sufferers of ms if this could be that disease and will mri scan tell me for sure?
