I've got a pain in my foot and it really hurts. it's when i tense my foot or put pressure on it. what could it be?

Foot Pain: It could be about anything. The first part of any examination is the history. How did this come on? Gradual or sudden. Is there swelling or other differences between feet? It the pain sharp, electric, throbbing? What if you just move it in circles without weight? Did you just change activities or shoes? See a doctor to get started on the investigation. Be a detective!!

Foot Pain: Is there any pin-point tenderness to the area? Any history trauma? How long? Sharp pain direct on bone could be stress fracture. Where on your foot is important to know? Any discoloration? Swelling? You should have this checked if this has been more than a couple days.
