I had a similar scenario to yours. When I had my ANA tested it was elevated. The doctor was sure I had Lupus. FINALLY, I had my thyroid checked...and was positive for Graves Disease. Once I started medication (Tapazole) the daily hives disappeared and only reappear if I get really cold. Thyroid is tricky however...it could test normal one morning and by afternoon test way off...so have your doctor order a couple different types of tests...T4, TSH, etc. Good Luck!
