<s>[INST] I have been having pain and swelling on the left side of my jaw, starting at the point where the jaw and ear meet.    I went to my dr. who prescribed Naprosyn, he also noticed a little gum irritation.    I feel tired and out of sorts and wonder if I have some type of infection.   What should I do? [/INST] Hi! Welcome to HCM.Pain and swelling is due to infection in the  oral cavity. Naprosyn is a analgesic.You must also take a full course of antibiotic to reduce any further progression of infection.You must get the necessary treatment for the involved tooth after the swelling and pain come down.Regards. </s>
