While Betadine (povidone-iodine) gargles can help reduce surface germs, they may not resolve deeper infections. Since your symptoms are worsening, it is best to see a healthcare provider to check for conditions like strep throat, which may require prescription antibiotics. In the meantime, please rest, stay well-hydrated with warm liquids, and consider over-the-counter pain relievers such as ibuprofen or acetaminophen to help you feel more comfortable.
