I'm trying to decide if I need to go to a and e,it's Sunday so fed courses. My throat is swollen I've been choking and vomiting, but feel it's not anxiety. I can visibly see the gaps at the back of my throat are smaller. I have a mildly underactive thyroid. On the lowest dose levothyroxine. Started taking regularly again and this happens as before. Last time I lost my voice a had to have steroids after being in allergic asthmatic state. Worried going that way again but don't want to bother busy casualty or wait for hours unless it's necessary or if can treat at home. Any advice welcome.
