dear user about your question i would like to tell you that these symptoms you mentioned refer mainly to have throat infection bacterial or viral.....your feeling of discomfort or itching of your throat should not make you worry as it is common symptom of common cold or bacterial infection of your throat .....about treatment of that you can take tylenol as it will help alot to improve .......you should also drink alot of warm fluids that helps also....you should also have bed rest and no effort that makes you tired .....you can gargle your throat with saline solution it helps to decontaminate your throat ......you can use chlorohexidine or betadine mouth gargle as it is considered antiseptic for throat.....some times we require blood test or throat swab if symptoms get severe but now you not need that.......if prolonged or high fever occur you can take amoxicillin as it is antibiotic has great role in throat infection.......wish you healthy life
