It is very likely that you will get it again after you have had it because it is mainly caused by bacterial or viral infections, but it can also be caused by allergies due to external irritants, and since bacteria and viruses cannot be completely avoided, and allergies cannot be completely avoided, it is very likely that you will get it again. If you have had pharyngitis before, you should avoid spicy and irritating foods, drink plenty of water and avoid catching a cold after you have recovered. Exposure to certain things can aggravate pharyngitis, such as special smells or exposure to animal fur, flowers and plants that can cause pharyngitis, so it is important to avoid exposure. For treatment, anti-inflammatory drugs or anti-viral drugs are mainly considered, and if it is caused by allergies, anti-allergic drugs are needed for treatment.
