I already have spd since having my DD two years ago and really don't need this! Symptoms are: exhaustion, piercing headache behind the eyes accompanied by waves of depression/agitation, loose bowel movements, nausea, upper abdominal bloating and sinus pain. It comes in a cycle, starting with slightly sore throat and exhaustion progressing to tummy upset. Has been happening more and more frequently over the last year. Went to the doctor and apparently all the tests are clear (vitamin D and celiac still to come back). I don't want to have anything wrong with them but a diagnosis would be a relief as I'm struggling to manage my daughter. I just don't know what else to do.
