HI, thanks for using healthcare magic There are different causes for sore throat such as sinusitis and post nasal drip, viral or bacterial infections, severe GERD, trauma. If you did not complete the course of antibiotics, it is possible that the initial infection did not completely resolve. Throat infections can be associated with enlarged node and other cough and cold symptoms such as nasal congestion and blocked ear. Treatment may involve the use of antibiotics (if it is thought to be bacterial though it is usually viral), a decongestant (would help your nose and ear) and antihistamine. The decongestant and antihistamine should be available over the counter. Though peer pressure can be great and feel difficult to manage, you should not let any force you to do anything that you are not comfortable with. It can sometimes help to practice saying no on your own or reminding yourself that you must do what is right for you first. I hope this helps
