(kind of.) I had an initial concussion in college 17 years ago, and this June a hairdresser pressed really hard on my scalp over my old injury about six times during a 5 minute shampoo. It was some kind of stupid aggressive pressure massage.

While it felt uncomfortable, I didn't tell her to stop because I had no idea it would lead to these crazy symptoms. Developed nausea, daily headache, dizziness, noise/light sensitivity, etc. Now ten weeks later I am much improved, but still not all better.

This has been the scariest thing I have ever experienced. I think I am done with hair salons.
