Suggest Remedy For Eye And Nose Injury

am 27 yrs old, 6ft and 88kg, was playing over the weekend and someone jammed their knee into my eye, got blurred vision and a nosebleed for about 1.5 minutes, all was fine after that, however for the past two days my spitum has mucus and dark blood in it, my doctor said i should not be worried that the blood will stop after sometime, however its now two days and everytime i blink or sneeze my, the back eye feels very uncomfortable as though it is congested and its twitching, plus when i blink i can feel as though am blinking through the nose, should i be worried, or will this go away.
