I'm smiling too.
It's so true that we can enjoy a normal physical function and completely forget that it used not to be that way (I've been there).
I'm also realizing how important it is for all of us keep a list of symptoms and their severity and frequency, and update it regularly, and particularly after anything changes (diet, supps, exercise, stress, illness or injury, angioplasty, whatever). This helps us track possible cause and effect with symptoms, though admittedly this is very tricky with MS.
In anticipation of my upcoming (I hope) but still unscheduled venoplasty, I started a list of ALL my symptoms, beginning with the worst and constant ones, down to the occasional and mild, even if I figured the symptom was unrelated to MS/CCSVI. The first day I came up with ten or so symptoms, but over the next week and a half, as I experienced symptoms I'd forgotten about, the list has crept up to 21 items!
By the way, I have only very occasional and mild tinnitus, but just experienced some last evening.
