It : It is hard to know what is going on without seeing the bumbs. I also don't know your age and family history. It sounds like you are describing varicose veins. Some of them are small and red. Others get big and blue. They can start when you're rather young, but tend to get worse with age.

Varicose veins are common in all women, whether physically fit or not. You should see a vein specialist for an evaluation. If the problem is not venous then they should also be able to determine that.
