if you have the feeling of clogged ear then you must get an ent consultation and will need an antibiotic , oral and nasal decongestant ,antiinflammatory.
You can chew chewing gums so that the ear drains through the tube which is connected between the middle part of ear and back of nose.
You should get done a test pure tone audiometry
and impedance audiometry to see whether you have the fluid collection behind the ears or there is any nerve deafness
In doubt do reply
