...it seems like a tentative link, but the muscles that you use to pop your ears when you swallow are controlled by your jaw....any probs with the jaw, these muscles can tighten up and not function properly so I am told. It is called TMD - Tempromandibular joint disorder (google is your friend here) and people reckon it can cause ear problems. A good TMD specialist can give you some better advice than me...caution though - these people aren't necessarily dentists or doctors - they could be physiotherapists or chiropractors etc... so you really need to hunt around to find the right person. I found a physio that specialises in TMD through the maxilliofacial surgen who removed my wisdom teeth. He refers patients to her before carrying out any surgery on the jaw joint and he reckons she takes away a lot of his business!
I didn't get any of this advice from doctors - it didn't come up either.....it was just from my own research on the internet!
Sounds like this time it was just your cold, but if you have a history of it you never know what else might be going on in the background...good luck!
