Calm Amongst the Chaos

Lily has been having these intense crying spells that seem to never end.
She cried Tuesday from about 3-6 then passed out. Yesterday it started at 2 and lasted until about 6:30 when she passed out and today she was doing good, I took her to school for a bit, but got called two hours later. She has been crying since noon. It is 2:15pm and I finally put her in her bed. She’s had Tylenol, I don’t know what else to do for her. She has some swelling, but no redness, no oozing, she has no fever. I don’t know what to do with her. It is so frustrating to have her screaming and have no idea what is wrong and no idea what to do. She had a crying fit the night before surgery and it makes me think maybe it isn’t the surgery. She goes through periods where she does this. I’ve taken her to the pediatrician, the ER, Urgent Care all where they say nothing is wrong. I don’t know if it is a neuro thing? Her meds haven’t changed. Sigh. No idea what I am supposed to do with her.
