I was diagnosed in 2010. The sunburn you feel on your face...is it on one side or all over? I have a symptom called trigeminal neuralgia. It is a nerve pain that typically is felt on the right side of the face. I have said it feels like a sunburn before, but the best example I can give is it feels like my skin has been removed there. I also feel it down my right arm. I try to keep the areas covered as much as possible (very hard to do with the face) as wind aggravates it. Even when I do cover my arm, it feels like the shirt is going to stick to my moist flesh--but of course there is skin there so it doesn't.
I've also experienced the leg vibrations--I can't tell you how many times I've reached for a vibrating cell phone that is just not there.
I almost always feel fatigued (as if I just got done with a weight-lifting workout) but I've found I can push through it if I have to. The hardest part is getting out of bed.
I have full body numbness, but other than the burning sensation on my arm and face, I am pain-free. I am so thankful for that. I hope your pain is treatable. Many MS patients smoke marijuana for pain relief. I tried it once and it's not for me, lol! I have no problem with others that get relief using it though.
Cognitive difficulty is common in MS. I used to be a public speaker. I am too afraid to do it now because sometimes my brain just gets stuck. It's like I know the word I want to say--I just can't get it out of my mouth. I've noticed I speak at a much slower pace then before. It's like I have trouble getting the words out of my mouth. Not to mention that talking gets me very winded! If I speak more than a few sentences, I need to catch my breath. It can be very frustrating.
From what you have posted, I would think MS is a definite possibility. However, it can take a VERY long time to get diagnosed. the doctors will try to eliminate everything else it could possibly be before diagnosing MS. I was "lucky"; I had over 40 lesions in my first MRI and they were in a pattern that is very consistent with MS. I went through all the tests and was diagnosed in about
3 months. That is very quick for an MS diagnosis.
The doctors may decide to put you on an MS treatment program. Most of them involve injections that you can self administer.
Did the steroid treatment help your symptoms? It has never helped me but I've heard it helps some people recover from relapses faster. MS "attacks" cause inflammation and steroids help fight immflamation...so it could help you recover faster. It can't cure you, but it may help your body heal faster.
Anyway, keep your head up! Not knowing is the worst. Once you get a diagnosis you can commit to a treatment strategy.
A frequent poster on here will tell you to check your diet. If you are not eating healthy, I suggest you start now. Even if it doesn't cure you, it will make you able to fight it more effectively. The body has amazing healing powers...if it is given the right tools to work
