Try brisk walking until you weigh less. That might help and keep you active. Do a walk/run regimen, and slowly build up your running. If you feel the shin splints then cut back on the running until they go away. Work your way forward without punishing yourself.

The "no pain/no gain" concept only works when we are very young and doing something we will be sorry for later anyway. For now, be careful and make your way slowly to your reasonable limits.

Good Luck!
