Kneed Some Help

This weather has my bad knee aching whenever I walk up stairs. And I probably climb over 500 per day, and it's not cool. The only benefit to running up so many stairs to catch trains and slide into class on time is that my waist has gotten slimmer. But it's not like I focus on such menial things. I probably need to go get an MRI done on this blasted knee. I'm scared to know how bad it is because I'm scared of someone puncturing a hole into my knee to fix whatever problem there is. That very thought makes my skin crawl. Anyway, keeping this short, I'm going back to my lovely homework. :D
