Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that ear soreness along with greenish liquid seems to be due to
Ear infection and fluid inside the ear seems to be due to infection..
Feeling of balloon in the ear seems to be due to fluid inside the ear..
I would suggest you to consult an Otolaryngologist and get evaluated and he can do an Otoscopic examination to confirm the cause..
He can be advised to take a course of antibiotics like
Augmentin, anti inflammatory painkiller like
Ibuprofen and Oral and nasal decongestants..
Antibiotic and
analgesic ( painkiller) eardrops will also be advised..
Avoid picking of ear as well as do not get excess water exposure like swimming..
Hope this information helps..
Thanks and regards.
