Blocked ear with ringing after speaking on a Nokia phone for 1 hour.?

I bought a really cheap Nokia mobile telephone the other day and yesterday I was discussion on it for nearly an hour. Afterwards I couldn’t hear properly and I noticed a ringing in my ear. Thought this would go away overnight but I have had it all day today and it seems to be getting worse. I returned the buzz and bought a different one by the way. Has anyone had this before – ear issues after speaking on a mobile? And how long for? I will go to the doctor Monday if I still have it.
