This is just weird...

I've been noticing for the last month or so that the hair on my left leg is falling out. I first noticed it a few days after I shaved. When I went to shave again, there was hardly any hair growth on my left leg below my knee. There were maybe a few stray hairs but nothing else. I didn't think much of it at that point. Well, I've shaved a few more times since then, but the hair loss is slowly traveling up my leg. I tried to google it in as many combinations of words as I could, but couldn't find anything really relevant. Does anyone have a clue what might cause my hair to stop growing completely on only one leg? At first I thought maybe it was hormonal, but that doesn't explain why it's only on one side. I don't think I really have any other symptoms to go along with it aside from the fact that when I sit with my legs crossed, that leg seems to go to sleep a little more than the other one. It's not really a big problem...in fact, I love having to shave less square footage! lol But it is a little big of an annoyance because it's just plain weird.
