I have these flare-ups sometimes when I get anxious where I feel my face heat up like I have a fever and my head starts throbbing like a headache without pain and I can just hear my heartbeat basically and get filled with this feeling of like overwhelming sickness and nausea. It goes away in a few minutes but sometimes it lingers and it was really scary before I realized it only happens whenever I get sort of anxious. I’ve been diagnosed with GAD for a few years now but this only started happening within the last couple months. Does anyone else get this and is it anything to worry about?
