I am a 17 years old, and i am having throat pain i woke up this morning with a painful sore throat abd it feels like mucus is stuck in my throat. A few months ago a had strep throat it went away bur every once in a while i get that painful sore throat and mucus. The pain is on the right side of my throat and feels like im swallowing a bunch of sharp needles. Really would like some advice thanks
