Hello - I am new to this board and fibromyalgia. I hope that I can get some answers here to help me understand. I am 28 years old now, but when I was 10 and wore big glasses I would often get unbelievable pain in the back of my head when I was running and the glasses would cause strain. There were two spots and they were sensitive to the touch. Over the years I started wearing contacts, but still get the pain when wearing sunglasses. I went thru countless pairs that all caused me pain and have discovered it is not the glasses but those spots. A tight hat will also cause these two spots to seemingly swell up and hurt. I think I notice it the most now when I am fishing which requires me to focus all day while wearing sunglasses. I also noticed after a day of fishing recently that my teeth were super sensitive that night when eating ice cream. I found on some other site where this was a cause of fibromyalgia. I am just reaching out here and hopefully someone has some experience similar to mine and can point me in the right direction.
