Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain severe ear ache along with leaking fluid from ear and crusty ear are indications of ear infection also known as Otitis Externa or Otitis Media depending upon the part of ear involved.. As it is already two weeks and it is leading to headache and also have drainage in throat that can also be a reason for ear infection as the ear and throat are connected via Eustachian tubes.. Therefore,I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like otoscopy, x ray, fluid culture etc can help in diagnosis.. He can be advised antibiotic and analgesic ear drops along with oral antibiotics and painkillers and at times manual drainage of ears can also be done for faster recovery.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
