Hi, I'm a 35 year old white male and over the course of 1 year I've developed several thyroid symptoms Thyroid disease runs in my family with my one sister being hypo, the other sister having Graves disease, my mother has Hashimotos and my dad had a brief thyroid problem in Vietnam. The symptoms I first developed were of racing heart, confusion, anxiety(no family history of anxiety or mental disorders), and elevated blood pressure. This slowly developed into flushed palms and fingers, anxiety attacks, irregular heartbeat, weight gain of 45 pounds over the course of 9 months, fatigue followed by at times bursts of incredible energy, worsening sinus and allergy problems, heel pain, gritty feeling in my one eye, mood swings, depression, trembling hands, and acid reflux. Strangely enough, alot of these symptoms started after I took an Avelox pill for a sinus infection and subsequently had a severe reaction to it. Another unusual thing is that I was treated for bronchitis two months ago with Zithromax and Prednisone and my irregular heartbeat, gritty eye feeling and heel pain all went completely away and have never returned. Over the course of this year I have been tested for everything from carcinoid to heart disease, all of which turned up negative and my thyroid hormones were normal all along. I finally insisted on having my thyroid antibodies tested and my thyroid peroxidase were 467 with normal being less than 35. In March I was told that my thyroid was enlarged but now it is normal sized with multiple nodules according to an ultrasound and I have been told I have an autoimmune thyroid condition-but not told which one. My questions are: Could the Avelox have triggered my thyroid to destruct and what will be the treatment now for me with elevated antibodies but normal tsh, etc. ? Thank You for your time
