ringing in ears from sinus pressure...does it evetually go away
How long have you had it, how long have you had the sinus pressure and have you had any treatment for it? Do you have a history of sinus problems?
It probably will go away eventually but I doubt anyone here can tell you when as it will depend on so many factors.
If you describe your problem with more information then you may get some helpful replies. Meanwhile, steam inhalation, especially with something like menthol crystals or eucalyptus oil might give you some relief (be careful not to scald your nose!).
