Did you have symptoms as a child?

When I look back, I had mild dysautonomia, heat intolerance, joints that would crack out and back in, but was pretty much a normal kid and it probably all could have fallen under an anemia diagnosis since I was anemic. Later in my early twenties, my SI joints would go in and out and cause some problems here and there and I became hypoglycemic, but controlled it with protein every 2.5 hrs and was fine, Thirties I felt better than I ever did, knew how to take care of my idiosyncrasies and had 3 kids by then. Two of my three had some of my "sensitivities", but the other had none. I can tell you that never in in my childhood or whole life until I got sfn, did I or my kids have nerve pain, crawling, numbness, or tingling. So I am having a very hard time accepting that a mutation is the answer to this. Obviously we were genetically predisposed to what ever happened, but life was pretty normal before this. Maybe I'm just in denial.
