hi sir .....i would like to tell you briefly yes.....infection of the ear can cause hearing loss but mostly temporary hearing loss and sometimes permenant....the most common cause is middle ear infection that called otitis media...this infection cause effusion of fluid and accumulation of this fluid cause hearing loss.. this fluid result from inflammation following infection...so dear user we should take it seriously...you said that it has been 2 weeks duration so it almost not along time to cause permenant damage...when accumulation of fluids lasts more than 2 month it may lead to danderius complication and severe damage of ear.....you may need to take the appropiate antibiotic so you can discuss with your doctor to do antibiotic sensitivity test.....grat importance to drain this fluid so simply next step you should consult ent ear specialist to drain this fluid and hearing may return normal and you will feel better after drainage of that fluid.....wish you healthy life
