But my knee doesn't hurt at all.  Well, there's a little part of it that hurts sometimes, but that was not this.  This was just a bizarre thing.  As far as going to a doctor goes, that won't happen.  I wait three months, after something begins to hurt, to call a doctor.  I do this with everything because I think it's going to get better.  My big toe started hurting in October.  I didn't do anything to it, but it felt like a knife was going into the bottom of it if I stepped on it a certain way.  I finally went to the doctor last month.  My toe is more swollen since I started doing the to exercises he gave me and I probably should call him and find out why it's swollen everyday, but I feel stupid calling because it doesn't really hurt anymore.  On the other hand, I want to know why it's swollen.  I just always feel stupid going to the doctor because I feel like they're going to tell me that it's nothing, which is good, but then I would feel dumb thinking something was wrong with me.  My hip hurt for a year before I went to the doctor and found out I had a tear.  Oh well.
