Thanks for providing more information.
As per your description,your symptoms -stuffy nose,cough,loss of equilibrium suggests the possibility of Sinusitis and Eustachian tube blockage.
And there is associated inner ear inflammation.
So in my opinion,i suggest you to consult an ENT specialist.
Even your blood pressure should be monitored.
You can take OTC Coricidin HBP .
If you have numbness in some part of body,vomiting,high blood pressure then visit ER to rule out Transient Ischemic Attack(Mini stroke)
Otherwise make an appointment with ENT specialist ASAP.
Hope this helps.
