Woke up this morning feeling as though the ire is something stuck on my throat preventing swallowing and breathing. I coughed and garbled warm water but nothing comes up. After more coughing started coughing blood. Appeared to be coming from my uvula. Went to the ER where they did a strep test and took x-rays for an obstruction. Both were negative. Swelling is continuing to be uncomfortable with minor bleeding. What do I do?
