I'm so sorry you're having a tough time of things at the moment... it's not just the symptoms which are frightening, is it? It's those creeping, wordless fears which rise up in your gut when you worry about what this episode might mean if, indeed, it signifies anything at all.
Sadly, nobody can tell you the answer to that, but at least you know you're among friends here who understand what you're feeling.
The fact that you mentioned infection might be significant, though: many people feel that infections can bring on a relapse, so try not to jump to conclusions just yet.
My experience has been slightly different -- I would always have numbness and tingling in my arms and hands
first, a few days before the early symptoms of an infection began to show. It was usually advanced warning that I was about to "go down with something".
Trying to describe the numbness was often very difficult: I used to say it felt as if I had been laying in an awkward position and my arm had gone to sleep, but it was that weird, detached, floaty feeling you get just before pins and needles starts.
I suppose it's pointless to tell you to try not to worry, Brock, but just remember you've got plenty of support here. Just don't forget to tell us if, (no, not if...WHEN!), your symptoms begin to subside,
