Lori, I am starting to do some reading online about central sensitization (CS) and trying to figure out whether Linda has it. Though she has been sensitive to certain external stimuli since the early 80's, she never had chronic pain until chemo in 2014. Her fibromyalgia symptoms began around 1983 and I relate much of her sensitivity to stimuli to fibro. She is highly sensitive to speed (driving 30 mph feels like 70 mph to her sometimes). She is sensitive to bright lights, e.g. even if someone is shining a flashlight at the camera on a TV show it really bothers her. And like I said before, she startles very easily. She is affected by tiny amounts of alcohol or marijuana, i.e. it takes very little to get her high. She does not experience pain from touch, smells or sounds as far as I know, though she has an acute sense of hearing and smell. I think I am still not sure whether she falls into the CS category exactly or not. Her pain is pretty much localized to her feet and just above the ankles and not so much anywhere else. For that I am very grateful and I hope it stays that way and she does not develop pain in other parts of her body.
