Hello, From your description you are seem to be presenting with signs of upper respiratory tract infection which could be due to viral infection, bacterial infection and hardly because of fungi, parasite, protozoa etc. If viral cause, you just need symptomatic treatment with nasal decongestants such as steroid sprays or antihistamines, analgesia for the headache + ear ache. Antibiotics are not necessary. Viral infection of the upper respiratory tract is more common in children. Usually when symptoms persist for more than 3-7 days (depending on your region), it is usually necessary to start antibiotic and continue beechams flu tablets (it contains the active ingredients for symptomatic treatment of flu syndrome). Hope this helps Dr Nsah
