I’ve been like this for months and months now. I have tried everything from going to the doctor to over the counter meds to get rid of this and nothing happens. Please help!!

Hi i have a sore throat, i have like a loose piece of skin or something near my tonsil which i have had checked about a year ago, dr saying it nothing! now i have this sore throat that i wake up with every morning for past couple of weeks, today my one tonsil is red and sore. Every website i look on says sore throat is first sign of throat cancer, that really scares me alot? does anyone have any ideas? please help im really paranoid and driving myself nuts.
