So sorry to hear about your symptoms. I am in the same boat as you. I don't have a dx yet either. I have had the cervical and brain MRI with and without contrast that turned up normal. Tons of blood work. The docs have ruled out Lupus, Crones, Arthritis, Fibro, Cronic Fatigue, Lymes and I am sure more that I am forgetting.
All tests come back normal which to my neuro that rules in MS even more.
All I can give you today is hope. Hope in the knowledge that the docs will find the answer, it might take time, but they will find it. Hope that tomorrow is another day and if it is ms you might just feel better. As I have noticed, with ms every day brings something new it may be worse or it may be better. And hope that you have friends to lean on either at home or online. In my experience a lot of the friends you need to help make it through are right here!
Good luck to you
