About a month ago the front wheel on my bicycle locked up when I applied the breaks--over the handlebars I went with my chin, lips and nose taking the brunt of things when I hit the asphalt. Needless to say, when all was said and done my face was a mess. I immediately noticed a hard, round, purple, marble shaped bruise appeared on my top lip where my mouthpiece usually rested. To my horror, once the swelling went down, I tried blow the horn, but found it impossible to get a note out [i.e. it sounded like all three valves were depressed 1/2 way and nothing but static and air came out]. When I try to "buzz" without the horn, only two thirds of the top lip [right of center] moves. I know it will take time and patience to rebuild. Any thoughts on getting things to do in order to get back on track again?
