Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain ear ache, jaw pain and also leaking sinuses that got some relief with Claritin D seems to be due to ear infection and as it is commonly bacterial infection, therefore it will resolve with antibiotics that can fight against bacteria.. Secondly along with antibiotics you should also take anti-inflammatory painkillers like Ibuprofen for relieving pain.. I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like otoscopy, x ray etc can help in diagnosis.. He can be advised antibiotic and analgesic ear drops along with oral antibiotics and painkillers.. Also avoid excessive water exposure to ears like swimming as it can exaggerate infection.. Avoid picking the ears.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
