A couple of weeks ago I got myself a pair of tights to keep me warm while running during winter. And since I've been running in them, my right knee is hurting, to the point where even simple walking down stairs is causing a significant amount of pain.
I've been doing all kinds of sports ever since I was little (volleyball, jujitsu, badminton) and since a year or 2 I started running. I've ran over a 1000 kilometers between September 2010 and September 2011, including 2 marathons. And all of this without any hint of an knee injury or even a sign of pain in my knee.
I run about 4 days/week, a couple of short (7-10k) runs and 1 longer run (between 15-25k).
With my background being computers and programming, I tend to approach this as a function with a set of variables. The variables include: weather, temperature, time of day, socks, shoes, clothing, how much sleep I got the night before, ....insert those into the "running" function and you'll get a good or a bad run.
And since the pain only started after I started wearing tights on my runs, I'm sort of putting those under suspicion. Has anyone experienced this or know that this is possible?
(PS: Yes, I am seeing a specialized doctor about this, just waiting for my appointment and wanted to get the question out there.)
