Pay attention to these sneaky symptoms.
Duyen Nguyen, an allergist at Memorial Hermann Health System in Houston, Texas.
Bad Breath
That bad taste in your mouth might not be from food.

It could be due to all the pollen in the air.
Your allergies may be the culprit.
This can potentially lead to chronic ear pain or cause you to feel off balance, according to Nguyen.

This, he added, can occur when mucous membranes in the nose are significantly irritated or obstructed.
Exhaustion
Feeling a little bit more exhausted than usual?
Not getting enough restful sleep could be due to allergy symptoms keeping you up at night.

It could also be due to what allergists refer to as allergy fatigue syndrome.

Voice changes
Clearing your throat or other off sounds can be another sign of allergies.
Oftentimes people are clucking subconsciously.
Unexplained Headaches
Increased sinus pressure from congestion just may be the reason behind your unexplained headaches.

This is due to the sinus cavities swelling, blocking any drainage that could relieve pressure, Wendt said.
Rashes
Seasonal allergies can cause flare-ups of chronic skin conditions like eczema due to increased inflammation.
Some individuals might also develop itching and rashes after direct contact with an allergen, Wendt said.
One such mannerism is what I call the allergic salute, Eitches said.
Youll often see someone use their index finger to push on their ear.
It could mean that the food cross-reacts with another allergen, Eitches said.
One example is ragweed and bananas.
It can typically be quelled bycooking the food.
And somestudieshave found that allergy medication may cause ear-ringing as a side effect.
If you experience this, it is definitely something to bring up to your doctor.
To start, make an appointment with an allergist to get tested to see what youre allergic to.
If symptoms are not well controlled with medications, allergy shots may be beneficial.This post originally appeared onHuffPost.
