Not for me. Had a blocked ear/eustachian tube this past week due to a cold and I could not get my right side tube to clear for anything. I used a decongestant and neti-pot to clear out the junk. Took me 2 days to do so, but the eustachian tube cleared yesterday. Using the neti-pot is controversial subject around here, but has absolutely helped me gain function of my eustachian tubes. I use Nasacort in both tubes after neti-pot.
It might sound strange, but I can now pop both my eustachian tubes with slight tensing of my jaw. My bad ear I seem to pop the tube in a few different places.
