You are having a flu syndrome which could either be rhinitis (allergic or infectious) or sinusitis
( can be diagnosed with your physician's assistance. To treat you will need analgesic
), chlopheniramine or any antihistamine to reduce any allergies and a nasal decongestant ( here i usually prescribe vibrocyl or marimar or prorhinel nasal puffs). I don't know what you have there. As for the infection since it is likely going to be viral just a few days of symptomatic management will get it gone. If after a few days it persist then it is likely going to be a bacterial infection (in that case, antibiotics will be of choice). Also try using general methods like keeping warm and hot soup or tea or coffee.
As for the abnormal hearing of sounds (tinnitus) it might be as a result of ear infection
or just symptom associated with the nasal congestion
. When this will clear off, you'll feel better.
In any case see with your doctor if symptoms persist
