Aha!

I have just diagnosed myself (maybe), and almost every piece fits. Credit goes to the jolly doctor for saying that this seemed the most likely culprit. It was after I asked the cause of and remedy for these that he responded with, "They're fuzzy wuzzy." After skimming this page and this page before thoroughly muddling my brain with the medical jargon on this page, I agree wholeheartedly. They are fuzzy-wuzzy. I hope it's really something else--preferably less fuzzy and wuzzy.
