Had stuffy nose faint sense smell bone marrow biopsy in august now nostril passage feel heavy difficulty breathing ct scan showed nothing other tests?

Almost understand: The question is a bit choppy and I struggle to see how the bone marrow biopsy fits in with the rest. Was the CT scan of the sinus? Stuffy nose, loss of sense of smell, congestion and difficulty breathing make me think of rhinitis, which can be caused by inhaled allergens or irritants among other causes. An Allergist can best determine cause and optimize treatment.
