Wanted to ask in here as I have a strange problem, and someone at work
suggested it could be sinus related (indeed my father suffers from
sinus problems but the head-pressure type).

Last week I was on holiday in Germany. On the last night, I was laying
in bed watching TV and felt fine but then suddenly realised I had a
very blocked right nostril. It was more frustrating than anything and
wondered if it would clear but in the morning it was still completely
blocked however my left nostril was fine.

Flying back later that day, the plane almost finished its climb and my
right nostril suddenly started running like mad. So much so, I had to
rush to the toilet for paper to blow my nose. Five minutes later it
seemed to dry up again but then on the descent the same thing happened
but this time it stayed runny. Also something that may be completely
unconnected - my right ear struggled to pop during the descent and I
had to close my nostrils and blow to be able to hear properly however
ever since I hear a faint pop whenever I yawn. Like I say, that bit
may not be connected.

Since I have been back, I have had a streaming nose that feels just
like a cold. Its making my head feel foggy and yet its still only my
right nostril that is running, the left one is absolutely normal. No
fever. No sore throat. No aches/pains, just a single-nostril-head-
cold!

On top of the above, I have a small, painful-to-the-touch lump just in
front of my ear. I assumed this was a swollen gland due to whatever is
causing the runny nose. It doesn't appear to be growing in size, and
it only painful if I press my hand up to the side of my face.

A chap at work who suffers from sinus issues wondered if it could be
related - especially due to the 'only on one side' factor. Is this
likely?
