Hi, thanks for using healthcare magic Infectious sore throat is usually caused be a virus and resolves with pain medication along with the other modalities that were suggested. If , however, you are seeing a yellow discoloration, it may indicate a bacterial source for the pain which may require treatment with antibiotics. You may want to revisit your doctor for a reassessment. There are non infectious causes of sore throat such as post nasal drip in sinusitis, in some cases of GERD, trauma, lesions within the throat. IF the doctor reviews your throat and thinks that a course of antibiotics is necessary then the symptoms, if due to bacterial infection should resolve provided adequate antibiotics are given and there is no resistance. If you still have pain despite adequate treatment, then it would be necessary to look for other possible causes. I hope this helps
