I have been on my thyroid medicines for the past 3 days and since then it feels like a ball is stuck in my throat. Also generally and even when I yawn, I feel like vomiting. I had ear infection recently and was getting treated from an ent specialist. I showed him my thyroid reports as well. After checking my t3 and t4 test results and hearing my symptoms (agitation, having a thought that I might die, sweating, vomiting, having negative thoughts, feeling scared, palpitation and loss of appetite), he recently put me on thyroid medicines after I was done with my medication for ear infection. Also my mother has thyroid so he said it's genetic. So, is feeling like vomiting after or without yawn could be a symptom of any disease? Below are the medicines the doctor prescribed for thyroid: 1. Cipralex 10 mg (after food at night) 2. Euthyrox 25 mg (before food in morning) both once a day.
