Update - We have the results of the biopsy. It is a benign tumor, but one that has potential to turn malignant with time, so it will have to be removed (along with the gland it is on). We will know more at her appointment on Tuesday. Thanks everyone for the kind messages! We swear by the Elderberry cough drops too, but hadn't heard about Arnica pellets! I'll definitely look into them for the future! Oh, that actually sounds good. Too funny! She's actually decided through all of her experiences to apply for nursing programs for college! I just found this at Whole Foods so we have it on hand for the next sore throat!
So glad your daughter is improving AND that you have answers! I learned a lot from this thread, too! Gotta be thankful for TLP!
