Headaches, Sore Throat, Ear Pain, Allergies, Chronic Pharyngitis
Thanks for your query,
The symptoms you have pushes me into the prime suspection of allergy , since the antihistamins or other antiallergics didnt work , the next in consideration would be Chronic Pharyngitis of infective origin.
To rule out the same i would ask you to get a Culture and sensitivity test of the secretions from the throat ( throat swab ).Also get your throat examined by a ENT specialist to rule out any structural defects like ulcers commonly seen in nutritional defeciency ( vitamin defeciency ) and growths .
Meanwhile,I shall suggest you to gargle with CHLORHEXIDINE solution twice daily after food .This will give you symptomatic releif by soothening the throat mucosa and inhibitng the infection if any.
Do avoid wine , as there are records of throat irritation due to the same , specially in already inflammed throat.
Hope I have answered your query. If you have any follow up queries I will be available to answer them
