Re: Fluid in the ear from a cold...
Gee, I don't know! If you have fluid, it would be behind the eardrum, so I don't know if it would help? BUT....do a check on eardrops and what's in them..if it's a decongestant (the kind in a spray bottle), then maybe it would be best to use that. The only problem if you decide to try them is to make sure it's not been shoved up your nose previously..just to make sure nose stuff stays in the nose. Just something I would consider.
If you're taking a preparation with decongestant in it, it should help open the eustachian tubes and aid drainage. Sounds as though you've really got it bad...I feel for you!
I think if you're not averse to herbal stuff, maybe the stinging nettle tea might help. I've not tried it yet...but could be worth a try to help aid in fluid build-up.
Hope tomorrow brings improvement!
It's all a matter of perspective!
