I am a 44 year old woman with a busy lifestyle. Who isn't these days.. Anyway, was diagnosed with Graves disease back in 2002. TSH levels so high that they were undetectable at first before going on methimazole and alot of beta blockers. Underwent RAI in 2003 and have been hypothyroid ever since. Finally after 2 years of my levels swinging back and forth I have been stable on 200mcg of synthroid for 3 years and doing well (exercising daily, etc) Now, all of sudden swelling, edema of the left side of my body more than my right but generally all over. Gained 15 pounds of water weight in 2 - 3 week period. Went to the doctor this week and now taking Aldactone to get rid of the water. Went for a ultrasound of my thyroid yesterday. Waiting for results. Besides the weight gain, fatique ( I am sure part of the water weight), and my left side of my neck tender and swollen and sometimes can feel funny when i swollow. Is it possible to have developed nodules or worse after my thyroid was ablated 6 years ago??? I thought I had this thing licked??
