Hi! I ve had a sore throat on and off for the last three weeks. It felt like any normal sore throat from a cold, so I didnt think anything of it. The second time was the same, and I assumed I may have relapsed on the cold. It came back today for a third time, but now it feels like the inside of my throat is bruised, and only hurts in a specific spot on the front when I swallow. Should I be worried about this, and what could it be?
