I am sorry that your daughter and family is going through such a challenging time. Google healing hypothyroidism naturally. It appears that she has a few health challenges. Please look into the paleo diet. Try to remove her from all gluten and grains- that includes rice and corn. Give it at least a month of consistency in following the paleo diet and you should see some positive changes. If you are use to eating dairy, grains, breads and sugars then it will be a hard change that should be done in phases- focusing on removing diary and all processed foods first. Try to eat only organic food if possible. Google paleo diet and get great recipes. Read my other post. Organic India makes a breathe free supplement that should help your daughter. I believe GAIA brand does as well. Get her on a high quality probitoic such as garden of life or Jordan Rubin's new supplement brand. Consult with doctor to make sure the herbs don't conflict with any medications that she might be on. Is highly recommend her seeing a reputable Natropathic doctor. Best of luck and God bless.
Any luck on what the cause is?
Plus I keep having stiff neck and headache across brow
