Kendall, I hope you do go to Boston, as they will be more familiar with these types of things and give you the best advice, as far as allopathic medicine is concerned.
I, too, hope you will try the Tea Tree oil and/or the acupuncturist we talked about. The Chinese have been at medicine for so many thousands of years, there is much to draw on there, too, and it doesn't all involve needles!:-)
There are good visualisation techniques to use with something like this, too. If you are interested, please give me a holler, email or PM.
And, don't forget to let your furry pal nuzzle up and give you "luvs."
Light, Love, and Healing to you,
