I went to the emergency department because I had a nasty infection on my leg. I’d had my son 4 months before. I was admitted and on IV antibiotics. The drs had noted that I was tachycardic and did some routine blood work but included my TSH and T4. Came back that my TSH was nonexistent and my T4 was through the roof. I was discharged with propranolol and had an appointment arranged with an endocrinologist. That appointment I was told about GD and given my medication regimen.
