Hello, The last few days I have been having a headache that comes and goes, it get exacerbated if I talk or laugh a lot. I feel kind of a numbness in my head and get a bit dizzy. The weird thing is that I feel as if I have something behind my throat and also a feeling of something clogging my ears from the inside. While this happens I also get kind of sleepy. I thought the headache was part of a stomach virus I had a few days ago, but the headache is lingering and I am getting all those other symptoms. What could be? Thank you
