It sounds like you have fluid in the ears from your cold. I would suggest taking an antihistamine and decongestant at the same time to help with the drainage. If you think you have it blocked with ear wax, you can get over the counter ear wax removal kits. Otherwise, if you are on the mend, you may just have to wait a few more days until it clears itself.
In the near future: If you are getting better now and then get markedly worse and are worse than you were when you first started your cold, you may have a secondary bacterial infection and need an antibiotic. If you get a fever and pain with your ear pain, you could also need an antibiotic for that.
Hope this helps!
