If your doctors have failed you, you can do the following:

1. Read all you can about shin splints.

2. Listen to your legs. Go running only when you feel like your legs won't torment you afterwards. Your injury may take time to heal, so you may have to rest them from running for many days or a few weeks at a time.

3. Find an alternative aerobic activity that doesn't impact your legs to maintain the excellent cardiovascular health you've worked hard to attain.

4. Balance your diet and get enough sleep to hasten the recovery process.

5. Go running on sand or grass or soft soil. Later, you can try hiking or running in all sorts of terrain.

6. Try interval training. Alternate between jogging and sprinting every few minutes. Maybe your legs just miss sprinting or need to strengthen its white muscles. Jogging too much overworks your slow-twitched high-stamina red muscles and weakens your fast-twitched low-stamina white muscles.

7. Try barefoot running or running on your forefoot. The human forefeet are better shock absorbers than human heels!

8. Stop taking pain relievers. Not only can they interfere with the natural healing process, they also give you a false notion of recovery.

9. Get a very gentle massage if your legs long for it.

I can elucidate on any of the above tips if you want. I won't lie, I hunt generous tips. There are excellent responses already. I don't want to invest so much time here, unless I see that you're not brushing off my answer ;)

Assuming you're suffering shin splints, you should be doing exercises to strengthen the muscles on the front of your shins so they balance the strength of the ones in your calves. To do so, sit or lie down with your legs in front of you and flex your toes toward your body. Hold the flex for 2 minutes and release the flex to rest. Repeat several times each day.

Second, as suggested by others, make sure you're running on really good running shoes, which will require going to a good running store. Buying running shoes at the local sporting goods store will not be good enough if you want to run long distances repeatedly. A specialty store will fit you with the right shoes, which will probably cost $130 - $180 per pair, and will only last for about 350 - 450 miles of running before they need to be replaced. Serious runners usually have 2 pairs and alternate between the two pairs.

Third, you may have increased your distance too rapidly. A typical guideline is to increase by no more than 10% per week.

Fourth, after finishing a long run, take an ice bath (or at least a cold bath) for 10-15 minutes. This will help the legs avoid swelling too much. Training causes microscopic tears in your muscle. Icing them helps reduce the over-reaction of the body and speeds up recovery.

After running a long hard run, if you can, try running a much shorter distance at a much slower pace the next day. This will help you with a quicker recovery as well.

From what you describe, it looks like you're not running on good shoes, and on a concrete surface (like roads). Go to a good running shoe shop, and have them examine the way you run. If it's a good shop, they'll put you on a running band, with video, recording the way you run, diagnose the way your feet hit the road, and suggest ways to avoid the pain.

Next to that, you might also consult a doctor, ensuring nothing is seriously wrong with your feet and lower legs. This is very important, as hardly anyone has perfect legs and feet, and there may be simple solutions, that will help you out, allowing you to push ahead with your training, without the pain.

Just remember that running is good for your stamina, but it might not perse be good for your knees and feet. Having good running material is very important, to ensure you don't injure yourself!

I hope this helps...

Based on what you have described above, it might be Medial Shin Splints which is also called medial tibial stress syndrome. This happens at the medial aspect of the leg, adjacent to the medial tibia in an area called the posteromedial border of the tibia.

The key factors that causes this are:

* Tight posterior muscles
* Imbalance between the posterior and anterior muscles
* Running on concrete or other hard surfaces
* Improper Shoes - inadequate shock protection
* Overtraining
---end of quote---

You can do self care by:
1. immediately decrease your training
2. do non weight bearing exercises to lessen the stress on your legs
3. You can do swimming, biking, and pool running instead.
4. Review your stretching exercises. Do gentle stretching on your calf and hamstring muscles
5. Replace your shoes with shoes that are are shock absorbent.
6. Avoid downhill running for this can aggravate your condition.
7. It is important to keep in mind not to run on concrete.
8. Do icing on your leg muscles after exercise
