Bless! You made me laugh. Be glad that you don't have a thyroid problem but I know what you mean when you have an issue and you think you hit the nail on the head!
Did the Doctor make any other suggestions as to what the problem might be?
Also this is something I have recently heard about. Apparenty the pollution here in Singapore is really bad and that does have quite an effect on one's skin. Since being here (5 months) I have broken out in spots on my face and just thought I was going through a second adolescence (how scary). Went home to London for a week and I swear to God within 3 days my skin had cleared up totally and I was back to clear face! Maybe that has something to do with it? Depends how long you've been here I suppose.
OR (I really should stop watching all these medical dramas) depending on how long ago you had the baby (I think you said several months) you may still be quite hormonal and that is what is causing some eruptions?
That is my medical opinion for what it's worth (my degree is in business management! :-)
Good luck.
