Recently, I ve been choking on almost everything: food, water, and even my own saliva. I had hyperthyroidism and I had improved drastically but my symptoms are coming back. Late periods, sudden heat flashes and mood swings. But I noticed my urine is cloudy, sometimes a little on the dark side. I am a 21yr female and I am occasionally sexually active (last time was two to three months ago and we used protection.) Is it a hormonal thing or is it something else?
