Hi Katie and welcome to NeuroTalk. I'm so sorry to hear of your ordeals but you've come to the right place. There are many very caring and knowledgeable folks here. I'm sure some of them will come along shortly to give you their opinions.
Your symptoms do sound like MS....but so many other conditions mimic MS that it takes quite a while sometimes to narrow it down. The doctors try to eliminate as many as they can before deciding on a diagnosis. The waiting can be maddening.
You're not alone.
