Dear Doctor,I hope you are fine and doing very well! I’m writing you from cold Afghanistan, behind thousands of mountain to seek your consultation.My sister 18YO is suffering from sore throat from the last two years, we met different doctors but none of them helped.It seems she is suffering from allergy, as she get sick once a month and complaining from sore throat with strong fever and blocked nose and pain in the neck. She also has the same complains when she eat paper, salty or spicy foods.I searched for medicines online but don’t know whether they will be suitable or not, please confirm if continues usage of Claritin 5MG/once a day, and cetirizine 5MG/one per day is fine for this patient.Or otherwise please do refer me to some medicine suitable for this patient.Thank you for your help in advance. warm regards I.S
