Shin splints, perhaps?

Yes, I believe it would be shin splints.. I know them far too well! And unfortunately I don't think there's much that can be done about them, they just like to come and go when they please. Try putting a heating pad on them a couple times a day to kind of loosen everything, see if that helps! good luck!

I would agree - make sure you have good shoes. My shin pain disappeared after I got good running shoes. In the meantime, aspercream does help alleviate the pain. Good luck!

Check into a different running style. I switched to fore-footed running and my shin splints went away, seemingly for good.

Something to look into. I used to dance and they thought that I had really bad shin splints until it got to the point where I had to crawl up and down the stairs in my house because of the pain. Turns out I have Anterior Compartment Syndrom, where the lining of the muscle is too small for the muscle itself. As you excercise, muscles fill with blood and swell when they work causing the pain to get worse. That muscle is still very developed in my legs, but if I avoid certain things, I don't have the pain. Things that trigger it: walking up an incline or walking long distances. I have found that when walking I have to flex my foot - working that muscle, and an incline can cause me a lot of pain the next day. However; if I run, I use my quadriceps to lift up my leg and land more on the balls of my feet, instead of my heels, so that muscle doesn't get used as much, and I've never had issues. I would pay attention to what you are doing when you get the pain and figure out how long it lasts. My pain would last for a couple of days at least because I had to wait for the infalamation to go down. I'm not sure about shin splints, but I'm thinking the pain is more during the workout a short time after.... hope this helps!

"Shin splints" is a catchall term for various types of tendinitis that affects the anterior part of the lower leg. Since there are a number of causes, there is no one solution that will work for everyone.

If your shoes are old, that's an obvious first place to start. You can go to a specialty running store and they can look at your gait and maybe make some suggestions.

If you are "speed walking" you can try lowering the speed and walking slower at a steeper incline.

It might just be a case of too much too soon, in which case, stopping the treadmill until the symptoms subside and going back to it very gradually could work.

In more persistent cases, it is necessary to see a therapist to analyze your gait in more detail.

If it is shin splints, it is often caused by an imbalance in strength between your calf muscles and the muscles in the front of your leg, or shins. While having the right pair of running shoes is essential if you have this or not, another important thing is to strengthen your shin muscles. To do this, when you are resting or relaxing at home, put your legs up on the couch so they are not bearing any weight. Flex your feet toward your nose and hold this position for 2 minutes, then relax for a minute. Repeat this 3-5 times and do this for several days in a row. You can also do this when sitting at your desk at work. Just stretch your legs out in front of you and flex your feet for 2 minutes etc. Doing this will strengthen your calf muscles. It worked wonders for me and now I never have shin splints. Good luck!

Yes, I agree with this. My podiatrist said shin splints can be avoided by strengthening the muscles in your lower legs. (Inserts too!) He also recommended a minimal running shoe to use a couple times a week to build strength, but that would probably be helpful after healing.
