Am I doing this right?

So, today is Sept 23rd and I'll write a little more real time after my first introduction post.

I'm sorting through what I think is high hamstring tendonitis. It never hurts that much but it's nagging and possibly the source of a lack of full power. I'm working every day now to strengthen and stretch my hamstrings. I just do not know if running is making it worse or not. Today is the day after running 9 miles and it's a little "loud". Though this was made worse by sitting in my car. I felt OK up until I drove in. Even my core and stretching did not really hurt.  Is it just the sitting? I'm trying to stand more at work. I have better shoes. I'm going to go on a walk after lunch and give the area some bloodflow.
