I have had a sore throat for a couple of days now. When I lay down, I feel like I cannot breath; I know I have had a lot of drainage as well. I woke up this morning and my throat had dark red blotches, and there was a lot of yellow in the back of my throat. The veins are a dark purple color, and are very noticeable. When I eat, it is very tender also. Is this something I need to go see the dr about or is it just from all the drainage?
