Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have pain in neck, throat and back . Well there can be many reasons for symptoms you mention in query like tonsillitis , sublingual gland infection , dental infection and muscle strain , but in your case the symptoms are probably due to tonsillitis . Take ibuprofen or acetaminophen for pain and apply warm compresses to neck . Kindly get yourself examined by a ENT Specialist as you will require antibiotics like amoxicillin or penicillin and analgesics or antiviral in case of viral infection. Don t panic as it is a common condition. Sore throat is most often caused by a common cold virus, but other viral and bacterial infections can also be the cause. In addition to Medications, you will require Home care remedies. Get adequate rest, Drink plenty of water to keep the throat moist and prevent dehydration. Warm liquids like tea or warm water with honey and do salt water gargles several times as day. AMPITREXYL is some kind of natural antibiotics , which should be taken after consultation with doctor . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
