Most likely the allergies are causing the issues because his sinuses and ears are probably clogged and causing him discomfort he cannot express. My daughter has had these issues since she was little. We have had her tonsils and adenoids removed, tubes put in he ears and they had to recently shave nasal cartilage so he breathing was better and the fluids drained properly. You may want to go see an ENT to make sure you don't have any of those issues. I can tell you it has made all the difference in the world.

Also you have to take into account the medications you use because some of them have different effects on our children. We can't use benydryl because it works the opposite way so we use hydroxyzine instead. She gets really uptight instead of calm.

I am not saying you have to go all natural but you have to try a medication and see what happens and change. Four coughs we have to use Delsym because the other ones make my daughter uptight as well. Trial and error sometimes.

Also if he grinds his teeth this can effect and compress on a nerve that is at the back of the jaw bone and right up on the inner ear which will cause a vertigo feeling compound that with allergies and Vestibulary issues and would be quite disconcerting. I have had problems with these first to components myself. I hope some of my spit balling helps

Most likely it is a Vestibulary issue stemmed on by his allergies because your sinuses and inner ear are connected and if you've ever had an inner ear infection you know how vertigo feels. Add onto that a feeling that your body is not grounded, who wouldn't it drive crazy. I do recommend the Benadryl also (at night time since it will make him sleepy ) but also see if a weighted vest or blanket makes him feel better and calmer.

I only use benadryl for the twins nothing negative from it
