Hello, Welcome to Just Answer and thanks for your question. You mention head exercise. Were you diagnosed with BPPV (benign paroxysmal positional vertigo)? Any other diagnoses? What medications do you take? What is your age?
Fluticasone (Veramyst) should help a lot with the symptoms. It will relieve a lot of the inflammation that is causing congestion and pain. The head spinning is another thing - from the BPPV. You should continue to do the exercises to reposition the matter in the inner ear that causes those symptoms.
