I had that issue, too quite awhile ago...like years ago. The problem for me was even when I got over the cold, I didn't want to get back on that blasted thing! I really lost a lot of ground when I didn't get back on it because it was months before I finally did and now I have a love/hate relationship with it. I rode it today for the first time since late November/early December and really gave it the "ol' what-for" but I didn't enjoy it. I did it because I know I have to do it now.
I hope you feel better soon and that you don't grow to loathe your bike like I did.
