otitis media is a middle ear infection usually treated with oral antibiotics not "drops". a loud ringing could be tinnitus often caused by an inner ear condition not something that drops would help. coupled by this unusual pain/pressure in your head it would be prudent to consider a higher-level medical evaluation from an ear nose and throat (ent) specialist. it would not be possible to determine a cause of your head pressure blindly over the internet.
i have otisis media (spelling? ) anyway i got meds and took them now i have head preasure. is this normal? . pretty much i went to the doctors because i had a loud ringing in my ear. she looked at me for like 5 minutes and said i had an ear infections. so i got the ear drops and took them. the ringing kinda went away. i still slightly hear it but now i have pressure in my head. specifically the side of the ear infection. anyway i'm getting really stressed over it. i keep thinking i have something wrong with my head. i have a spot where it feels like someone put their finger on my head. its so annoying
