My sinuses and I think eustachian tubes have been congested for a couple of months now. I'm quite positive it's congested, but what I'm not sure of is... do congested sinuses or eustachian tubes cause a sort of sleepiness effect?
I don't feel tired, but I feel this weird sleepiness feeling like I have heavy eyes. It's like the kind of feeling I would get if I take a type of medication that causes drowsiness, like an antihistamine or something like that, but I haven't taken any medications.
Another way of explaining I think would be kind of like a "foggy" mind, like I need extra effort to concentrate.
Has anyone else with sinus problems experience this type of symptom?
