Yes can be others: Gastroesophageal reflux (gerd) can cause irritation of the throat if not treated appropriately. There can be acid reflux and non-acid reflux as well so it is important to follow with a GI or ENT doctor to make sure that you are treated appropriately. Viral illnesses such as a pharyngitis can also cause raw red throats. If you are not improved over a week, you should follow up with your doctor.
