I had my hair colored 3 days ago. The next day, I noticed my scalp was extremely itchy and flaky, I seemed to have bumps all over my scalp tender to the touch, and then a painful lump behind my left ear. It hurts to turn my head to the right and is now associated with a frontal headache. I am 38, weigh 154lbs, was recently diagnosed with Graves disease. What should I do?
