Dealing with sinus/chest infection. My left ear is clogged/stuffy. Cant hear out of it. Is it safe to use peroxide? What should I do?

URI. Sounds as if you should see a doctor and be fully evaluated, particularly if you are having any trouble breathing. You don't say what you want to do with the peroxide, but if you are putting it into the ear would recommend not doing this until you are examined. Have you tried a decongestant? Used a sinus rinse? Please see someone soon and get better. Best wishes.

My left ear is clogged. Dealing with sinus/chest infection. Can I use peroxide to delight? What can I use so I can hear out of it again?!

Clogged Ear. If it's due to ear wax, debrox drops and bulb help. For congestion, saline sinus rinses and an antiallergy with decongestant can help ( zyrtec-d, claritin-d etc). Read more...
Sounds less like wax. Your symptoms are most likely related to a condition called som (serous otitis media). This is fluid behind the eardrum that gives you a sensation of fullness and can reduce hearing like a big ole piece of wax. A maneuver called a "valsalva" can sometimes clear it better than a pill. Hold your nose and blow gently against the blocked nose to "pop the tube" and let fluid escape & air in to ease it. Read more...
