Sprain or fracture of foot confused.

I've feel from my scooter and my foot got jammed in between ground and scooter in a 180°(appx) after that the swelling was on a certain area on foot only I wore my shoes and attended a lecture of 3 hours then came back home and saw the swelling was distributed among the foot region only. There is no colouration of skin or no cuts the main pain area is the foot only there is no pain beside that area. The pain was MINIMUM WHEN I FELL OFF AND NOW AFTER APPLICATION OF VOLINI AND MEDICINE THE PAIN IS GETTING LITTLE BIT INTENSE AND FOOT GOT SWELLED AT TGE DOWN PORTION ALSO , BUT MY JOINTS AND ANKLES ARE ABSOLUTELY FINE WITH NO SWELLING AND NO PAIN ONLY THE FLAT AREA OF FOOT IS PAINING WHEN I PUT CERTAIN AMOUNT OF FORCE OR WHEN I STAND UP. THER IS ABSOLUTELY NO COLORATION
