I am SO sorry that you are dealing with all of this and hope and pray that you get some much needed answers real soon
As the others have already stated, you are at a point where many of us have been or still are unfortunately. I don't suffer from MS but suffer from another neurological illness that is fairly similar and it took me 4 and a half months to get an accurate diagnosis. I had to go to 5 different hospitals and must have seen about 50 different doctors before I got a proper diagnosis.
I totally understand some of what you are going through and am always here for you if you ever want to talk. I understand how frustrating it is whilst you are waiting for a diagnosis and I think sometimes, it is better to know what is the matter rather than not because whilst you are waiting for a diagnosis, you can convince yourself that you have anything. I did that quite a lot before I was diagnosed and it was probably the worst thing that I could ever have done but I wasn't getting answers from any doctors so me and my mum decided to do some research ourselves.
If you aren't happy with your current Neurologist, I would really suggest getting a second opinion. That is what we did and I know many other people that have and it has been well worthwhile.
Hang in there, I know how frustrated you are but once you get a diagnosis and a doctor that cares, it is well worth the waiting!!! We are all here to support you whether you have MS or not.
Please keep us updated when you can and I am keeping you in my thoughts and prayers!
