Ok, well I'd already have to say no. But here is why I am asking this question. As of late, I have been doing much riding. I actually put over 400 miles on the bike today just riding up to Albequerque, NM and back to El Paso, Texas. But for the past couple of days, I haven't been able to feel like my middle and ring fingers on my left hand. You think it could be from riding too much? or like since my back is completely blown out at the lower portion? (though I was told that won't have any effect on my upper body) The back should only effect my lower extremedies, which explains why my right leg goes numb like 6-10times a day for like 30-45 minutes at a time. I just hope it don't happen when I'm riding though, but luckily it's only the rear brake on that side!
