Hi, the sensation could most probably be due to tonsillitis. Throat pain, difficulty swallowing, fever, scratchiness in the throat, post nasal drip, malaise and loss of appetite are symptoms of tonsillitis. It can be caused by bacteria like streptococcus or it could be a viral infection. Bacterial infections need antibiotics. There are tubes called 'Eustachian tubes' which connect the middle ear to the throat, this balances the air pressure in the ears. This tube can get blocked due to infections of the throat, which can give lead to a feeling of fullness in the ears. Consult your primary care physician who will do blood tests and take a throat swab to determine the cause and prescribe appropriate medications. Regards.
oh and if I pree my throat a little I could feel a pain in my right ear
