Someone once said, and I take this to heart (and took it to heart before my mom got diagnosed, which is how she got diagnosed) that it is important to go to the doctor if something concerns you b/c the LAST thing you wnat to hear is a doctor say "if only you came in sooner with your concerns.....".
When my mom had her cough, I INSISTED on the chest xray. The doctors were like "if everyonoe with a minor dry cough had a chest xray, blah blah.". I said that's nice, but my mom is MY mom and she WILL get getting a chest xray. And then the fun began!
When in doubt, get it checked out.
Of course my mom and I were "laughing" the other day and reminiscing about an inner ear infection she had 6 months prior to diagnosis whihc was bad and how if she had that EXTREME dizziness today she would be sitting in a MRI machine to make sure the viral infection was not a brain mets
