spitting up/mucus out of nose

Hannah
Is this normal? I'm so irritated right now because I've brought this concern up with my doctors numerous times but today my son had full on spit up & mucus come out of his nose only & he was clearly in pain. His eyes immediately watered & it sounded like he was choking. The doctors have given me no advice & just keep telling me "this stage will pass in time" but I seriously can't sit here & watch my son go through this once or twice a day. Has this happened to anyone else or is there anything I can do? I'll take him to the ER if I have to but our ER is just awful. TIA 
**my son is also only 3 weeks old
