Hello dear... All these symptoms suggest that you might be suffering from upper respiratory tract infection. Recurrence of the symptoms suggest that the causative agent has not been completely eradicated. Tiredness, lack of apetite & loss of weight can be attributed to the chronicity of the illness. There is a connecting tract (known as Eustachian tube) between the nasopharynx & middle ear through which infection can spread to ear. Also obstruction to this Eustachian tube can lead to ear pain by un-equalisation of pressure between the nasopharynx & middle ear. The management consists of: 1. Drinking of warm fluids to reduce throat pain 2. Antihistamines to provide symptomatic relief from cold. 3. Nasal decongestants to relieve obstruction. 4. Analgesics to take care of headache & fever(if any) Investigation like complete blood count & X ray of paranasal sinus will be helpful in clinching the diagnosis. So...it will be better to consult an ENT specialist for proper physical examination & further management. Wishing you a speedy recovery. Thanks & take care.
