Hi There. I Hope You Can Help Me. My Feet

Hi there. I hope you can help me. My feet ache, It's a tingling sensation on my soles and at times its an strong pain. I'm on my feet at least 8 hours a day, and I stay active. When I'm on my feet or working out i don't feel pain or tingling. I feel pain after I sit for a while. I guess when I'm not using my feet that's when the pain begins. It usually takes me a while to walk normally I usually wobble because of the pain. What can it be?
