every morning that i wake up I have a persistant headache. It tends to get worse throughout the morning and then subsides in the afternoon. My nose also tends to be blocked and has a slight tingle. I also wake up in the early hours of the morning and sneeze consistantly for about 10 minutes then it goes away. Is there any reason why this is happening? It has been going on for about 4 months now, since i've started working and studying 7 days a week.
