Hey, I was going to add (but the storm interrupted), out of interest, the time frame this happened in.

Swallowing problems started about Jan 2006, and started improving around November 2006. Peeing thing started about Feb 2006, stopped about May. Then in Oct(?) 2006 I had a 6-week attack of extreme vertigo, the single most disruptive thing I've ever had in my life (apart from breaking my arm). Not dizziness, I mean the entire world spinning around day and night. Good thing my apartment's tiny, 6 weeks staggering from bed to loo, hanging on to furniture for dear life. When the vertigo left, the swallowing began to lessen. I wonder if they're all connected?
We've had a few others on here with vertigo and btw, if you get that (I sincerely hope you don't!) do the exercises, they help no end.

You've started me pondering now, I've never thought of the three things as being related, but maybe...!
all the best
