Since how long are your symptoms?
Were any investigations done?
Any significant past medical history or surgery?
Do you have sore throat, headache, night sweats, vomiting, constipation/diarrhea, abdominal pain, breathlessness, loss of appetite?
Sore throat, headache, breathlessness, loss of appetite, fever, chills, body aches and sun burnt feeling of skin points to an infection (which can be a bacterial infection of viral). The intensity of the symptoms if high grade, points to the bacterial infection and an attention of a physician. So your symptom severity would dictate, whether you need to consult your doctor early (which may also need investigations) or can do a watchful waiting, if the symptoms are very mild. Pneumonia can be a possibility and will warrant an examination by your primary care physician.
