I heard a pop in my head yesterday after pressing on a bump I found a bit above my temple on the right side of my head. I didn't have any pain, but my head felt very weird and there was a lot of pressure and not sure if that was due to me panicking about it or not. There's also a bigger bump on the back of my head on the same side but a tiny bit above my hairline. I now feel very weird today like there's pressure all over my face like my nose, eyes and temple area. Is this something serious?
