Welcome to Healthcare magic,
First of all i could not understand your English properly.
anyways what i understood is 6 months back you had running nose and had blocking sensation in your ear. now since one month you have pain in ear.
The reason can be your eustachian tube is blocked and causing pain in your ears. you might have developed ASOM meaning development of pus in your ear (there can be collection of sterile fluid also), if you do not go to ENT specialist
in time it may rupture your tympanic membrane and become chronic. so as early as possible consult an ENT surgeon who will drain the pus and put you on antibiotics and analgesics.
