I just wanted to share what we've discovered with our 8yr old son. My son has had these type symptom during allergy season but not as intense as this year. WELL this year we started giving him Allergy Immunotherapy drops and his symptoms increased majorly. I've referred to it as OCD but honestly its a mixed bag of OCD, vocal tics, stimming/sensory stimulation. I connected the dots and had his histamine tested. Mind you, he had barely any noticeable symptoms. Occasional sneezing or cough. His histamine levels were 4x the high normal. Histamine is actually a neurotransmitter and can cause neurological symptoms. Do some research on Histadelia kids. Describes my son to a T. Work with a Functional MD or ND who understands the methylation cycle and other contributing SNPs.
I would suggest getting a Blood Histamine test. We just had one for our son by Dunwoody labs. It included histamine, DAO and Zonulin (zonulin was optimal so not a Leaky Gut problem). We ran genes through 23andme a couple years ago which is helpful information (still requires research, trial and error). Dr. Amy Yasko (google her name) has an online forum and free online books which are very helpful regarding gene errors and the methylation cycle. If our histamines are too high there are some reasons behind that which can be supported by understanding your methylation cycle.
You can read up on Histamines and how they effect us. Some people have issues because of low histamines and others because too high. Here are two good links.
