Greekdude. I am just reading this now. I hope your son has had treatment in the mean time. Your son sounds like mine. Also anxiety, OCD, sleeping with me, sensory problems, periods of sudden severe separation anxiety, and AN symptoms started at age 11. Diagnosed at age 12 following major strep induced flare. Treated with antibiotics which did not do much, then tonsillectomy and IVIG. After 4-6 months he was a different kid. No more anxiety, OCD, food restriction, sensory problems, sleep problems. He is now 18 and he gets symptoms sometimes with infection but they go away. About once a year they don’t go away and instwad continue to get worse. He then gets high dose iv steroids and that takes care of it.
I hope your son has received treatment, if not I do recommend IVIG. They also use rituximab now.
