hi. i play american football and i got a hard hit few days ago. the hit was on the left side of the foot, just below the side part of the knee . 2 days it was hurting but there was nothing visible. now i see a wound that is 5 cm in diametre with blue, dark blue, yellow colors. the strange thing though, is that i dont feel anything in this zone. when i touch it, i can feel it with the hand , but the skin on the foot doesn t feel anything. could you tell me what possibly happened? a fu%ked up nerve or something? thanks in advance.
