My ear is clogged and i dont know whats the problem?

so for the past 2 months probably my right ear had felt almost like there is a rock in it. it feels like wax and if you oush on the ear it feels more clogged. if i sleep on my right side and put pressure on the ear when i wake up it feels very clogged. it doesnt hurt at all, it is just very annoying. i went to the doctor about a week ago and he looked in and said i have healthy and fine ear drums and that there is very little wax in both ears. he said it is probably fluid behind my ear drum from congestion. i am not congested really at all. he told me to take nasonex and over the counter allergy medicine to fix the problem. well would those really help? what should i do?
