Actually yes, it most definitely could be related to the cold for a number of reasons (nasal/sinus congestion, inner ear issues, general fatigue and malaise).
I'm dealing with the same thing as we speak, I'm getting over an upper resp infection (quite a wicked one), and any quick head movements, or getting up too fast, causes some dizziness.
Just take it a little slower for a couple days. Even though many of your symptoms are gone, you're still recovering.
If after a few days you don't notice an improvement (or if you start having pain/drainage from the ear or a fever), then get into see your doctor. You may have an inner ear infection that will need treated.
Hope you feel better soon, let us know!
Ok. Yea I'm just worried I have like an inner ear diease or something. You don't think it could be bppv right?
It's not just like a lightheaded feeling. It is like a spinning feeling I can't describe it.
