###Human: I am suffering from ear pain, and feel like the whole head is blocked. Why? ###Assistant: Hi. It looks like you have developed what we call as eustachian tube catarrh. This tube ventilates both the nose and the ear and can get blocked due to allergy or sinusitis or in any upper respiratory infection such as common flu. If you have allergic issues, it has to be adequately treated. Tablet Sinarest (a combination of Acetaminophen, Chlorpheniramine, and Pseudoephedrine) one tablet two times a day, i.e., 12 hours apart for one week can be considered. Otrivin nasal drops three drops three times a day for 10 days should also help. Valsalva exercise 15 to 20 times a day. Steam inhalations also do give a little relief. Antibiotics and painkillers will not help as it does not treat the problem. However, complete the course of your antibiotics and do not stop them halfway. I hope this helps.
