Sore legs, need advice

It could be any number of things. But I would start with the shoes. I would go to a running specific store where they will find shoes made especially for you, and I think you will see improvement in your knees. My disclaimer though, is that I am no doctor, just a running fanatic. Feel better!

Goood call! My first thought would be shoes, too. You may have worn yours out. Even if they look OK the cushioning has probably gone.

For first-aid, soak yiur legs in ice. Or water as cold as you can stand it.

Your problems could come from a number of areas. My first advice to you is to make sure that you are running in quality shoes. Good shoes can make the difference between a good run and a painful run. I suggest you go to a specialty running store for some professional advice. Shoes bought at sporting goods store are still quality shoes, but if you require a stability shoe and are running in a neutral shoe (for example), you may not be helping the problem. Go to your local running store and find out the type of shoe required for you particular run style. It may cost a few dollars more, but if you find a good shoe that fits you well, it is worth the cost. I ran in four different kinds of shoes before I found a pair that I am really comfortable in.

Also, keep track of the miles on your shoes. After 300 - 350 miles, they begin to break down and this can also cause problems.

Good Luck.
