@dloos, @laja I think you and others in this thread may find it interesting to watch Dr. Sletten's video explaining Central Sensitization Syndrome:

It may offer insight to why and how sensitivities can come about and how to calm them. I was diagnosed with CSS and prior to that I lived a period where I didn't understand odd symptoms such as sensitivities to light sound touch and pain in general from stimuli that normally should not cause pain. Dr. Sletten helped validate so much and helped me realize I wasn't going crazy. Many doctors aren't educated on or aware of CSS. Do you think you may have CSS? Are you being told by doctors that no one understands what might be wrong with you and why?
