Kicked A Wall. I Felt The Pain At The Instant

Kicked a Wall. I felt the pain at the instant on the right foot, but it subsided and in the morning there was an agonising pain. I am able to rotate my foot and can't feel anything out of the ordinary with bones and muscles seem strong. But until I stand and notice a bulb on the right side expand angamnd the veins pop out extraudinarily. I can't place much pressure down and my body goes into sweats and the veins deepen.
If I move the foot toward the knee without assistance I can't get very far.
What may be the issue?
