I have blisters lining the back of my throat. It started yesterday. I have gotten blisters many times before. It normally goes away in a day but, this time it didn t. I woke up this morning feeling horrible. The blisters and orange-ish and red-ish. It hurts to talk and swallow. I have a temperature of 99.4-5. The pain only stops when I m either eating or drinking. I haven t gotten a flu shot and I am kinda freaking out.
