Can you please provide more details related to your symptoms? Are you congested? Does your ear feel "plugged"?
Examples of conditions that may cause a conductive hearing loss include:
Whatever you do, do not use a Q-Tip in the ear canal under any circumstances. If your problem is caused by wax, using a Q-Tip will only compact the wax tighter into the ear canal.
If you are congested or your ear feels "plugged" you can try an over the counter decongestant.
If your symptoms don't disappear within a few hours with use of a decongestant or if pain develops, seek a consult with an otolaryngologist. As it is a holiday weekend, you may want to been seen at an urgent care, especially if you develop fever, severe ear pain or drainage from your ear.
