You might want to consider getting some MSM powder for your twice-a-day smoothies.
The reason why I mentioned twice a day is because it takes 12 hours for the body to eliminate MSM. For best results, MSM should be taken with Calcium Ascorbate powder (main ingredient of Ester-C).
Just read the enclosed link about MSM from Natural Zing. Then use Google to check out facts about MSM and runners. I have been using MSM for about 18 months -- great for faster recovery especially after my long runs.
If you don't mind, please tell us about where you run. Running on concrete sidewalks is the worst thing you can do for your legs. Also, running along cambered curb on the streets is bad for your knees since one of your legs would be lower than the other. Ideally, it is best to run on a level and soft surface. Do you have a park teeming with sidewalks? If so, try running on the grassy part next to sidewalks.
Of course, your running shoes could be another factor. It won't hurt to be seen by a running specialist. Is there a running shoe store near your home? Maybe it is high time for you to pay a visit if you are serious about running.
It is always best to lay off from running for the duration when you are in serious pain.
Take it easy!
