I am having the same problem. The pain in the evening is so severe that I don't want to swallow. I went to the doctor yesterday and he couldn't find anything wrong with my throat like strep, or anything. However, he did say that my uvula was abnormal looking...? I wish there was an answer for this. It is very painful, and nothing I do takes away the pain. I just look forward to the daytime hours when the pain seems to subside. It's very unusual, never have been through anything like this before.
