Personally I avoid using herbal formulas when possible during nursing, which I assume you are doing? While they can be used during pregnancy, nursing, etc. we use them very cautiously and avoid them if they are not entirely necessary. If your symptoms are mild enough, acupuncture, moxabustion and some dietary change should be fine. Many women get these issues after giving birth as they lose blood and vital essence leaving their spleen and/or kidneys challenged for a short period of time.
For dampness you should find this article on TCM dietary therapy helpful. You can read generally about dampness on the page I linked to and the page before that you can read about foods which benefit the spleen/earth element generally.
For dampness the main thing is to avoid dairy, fatty and greasy foods and alcohol - but also irregular eating, eating too quicly, and eating complex meals or at late hours. If you have coldness as well going easy on raw foods and/or juices would be appropriate. Instead you want simple easy to digest meals (root vegetable soups are a good example) and possibly some drying spices such as cinnamon added to oatmeal perhaps for breakfast.
Moxibustion would also be appropriate which you can do on your own at own with a moxa roll (your acupuncturist should be able to give one to you).
