See, I've had troubles with knee pain for a few years now. My left knee is worse than my right. The pain comes and goes. Sometimes it's just a little painful and sometimes it's unbearable. For the past few weeks it's been unbearable. About a year ago, I got a cortisone shot for it, and that really helped. I decided to get that done again last week. I received the shot on Thursday. Today, it finally stopped aching--you know the way you ache after getting a shot? Anyway, when I went to ward prayer this evening, it came time to kneel to pray, and I thought to myself, "oh boy, this is going to hurt!" But it didn't! I made it through the whole prayer and it didn't bother my knee at all! Modern medicine is amazing.
