<human>: Hey runnit!

I love you guys. Please tell me if you think this sounds like an injury or if I just need to build up strength in my knee! I'm scared!

I'm gearing up for a half marathon in a month. I've been running 4 miles slow about three times a week, which is my normal routine.

Now I've added in a long run of 6-8 miles on one weekend day. It seems like after/during the second long run my knee started to hurt/feel weak.

Lately, my left knee has been starting to hurt on every run. At first it took several miles, now it is within the first mile that it hurts. I've been taking 2-3 days to rest it these last two weeks, icing on and off for 20 minutes at a time, then trying to run 4 miles to see how it feels. Seems like it's getting worse. Like I said, I can't even go 1 mile without pain.

I started doing a slow 4 miles yesterday and realized that if I switch to a less knee-lifting stride to a more back-pushing stride, I didn't have sharp pain, but my knee still felt kind of odd. I was able to finish the 4 miles without sharp pains, but today my knee is a little sore/cranky.

I have been lifting weights 3 times a week for the past two months. My boyfriend said I should be feeling sore the day after a workout, but I think I've been going too light with the weight, so I don't think I've injured it that way.

Anyway

Can you provide a brief overview of the text?
<bot>: Knee pain is getting increasingly more common when I run even a little bit. Changing running style doesn't incur sharp pain, but I'm wondering if I should continue on like this.
