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.
