My throat

So for the pass couple of days I've been coughing, my throat hurts so bad. Every time I cough I feel like I'm bleeding from how bad It is and now I found a lump and it kind of hurts. I feel like I can't breathe when I sleep and when I look up. My friend is a CNA, she said it can be my thyroid gland acting up. Does anyone have any problems with thyroids that experienced this? I'm going to the doctors tomorrow morning.
