Hello! I am translating a medical text which has the following: "...this treatment significantly improved nasal obstruction, rhinorrhea (runny nose) and ear fullness." I'm not sure whether the "ear fullness" is a sensation produced by swelling in the Eustachian tube or the inner ear, or whether it is actually a deposit of mucus or pus, for instance, etc. in the inner ear. I therefore do not know whether to translate "ear fullness" as “hinchazón” or “infección”, or what. Suggestions appreciated.
