How can I get relief from ear congestion?

I had a bad cold last week and flew home on Sunday. As the plane descended, it felt like all of the pressure from my sinuses went into my ears. Now, one ear still hasn’t cleared! I’ve tried heat, steam, chewing, yawning, decongestants, sinus meds, etc. Online research has yielded horror stories about some folk remedies (like ear candling). I would appreciate any advice.
