I was at a wedding reception/after party last night, and the DJ said he wanted to see break dancing. So me being myself, I volunteered. I spun around a few times on my head, and then other dance moves. Then, about 30 minutes later, I went to the bathroom with a headache, and feeling nauseous. I felt my head and on the top of my head, and pretty much centered on the top of my head, I felt either an indentation, or 2 bumps in line with each other making i feel indented. My headache got worse and its been about 20 hours, and I still have a headache, even after taking Ibuprofen.
