I have a 21 yr that has had the following symptoms for years with no results from doctors and test. feeling of low pressure but is fine when taken, body temp changes with her usually feeling cold, nausea, migranes, dizzy, tires easy, low bone densityand she gets pleursiy. Yes I know she is young for pleursiy but it has been confirmed by at least 2 doctors. She did at younger age brake out in blisters from over heating when in an air condition car but the only time it happen. She does sweat and is not cytis fibro (spelling?). She has had several fully throid tests all back normal. Tested her blood sugar and blood pressure for at least 6 months every day and it always came back fine but the symtoms were still present. She is not over weight or underweight and she eats good foods, meats vegatables for examples. She has been tested for allergies air borne and food and yes she does have them. She has been on a full allergy programs for at least 2 yrs and some improve in less migrianes but everythings else stayed about the same. I am hoping someone can really help her when so many doctors can not.
