My legs usually feel tired and the knee area hurts or sometimes the lower muscles hurt in the leg? - tire leg

What can I do to feel better. I visited several doctors and they told me I needed to practice. But I have only legs and feet you feel more tired .. What do you mean? I even asked ax ray and the U.S. Commerce Department said .. it was not necessary, but he sent me a blood test, which was clean ... and the pains come and go in and out of the 1 ½ years ago ..
