Hello there. So recently I had a chest x ray with contrast dye, the day after I had a small rash on my neck so the doctors gave me Benadryl and it has helped. It's been 4 days now since I had it done and now my throat feels like there is a lump in it or something stuck in it. I went to the ER last night and the doctors looked in my throat and said there was nothing blocking it and it should subside but i woke up today with the same feeling. Could it maybe be related to anxiety? It's making me worried.
