Your persistent symptoms suggest you need long-term controller medications rather than just quick-relief options. First, stop using the decongestant nasal spray immediately, using it for over five days causes rebound congestion, worsening your blockage. Switch to a steroid nasal spray (such as fluticasone) and saline rinses to reduce nasal inflammation. For your asthma, relying on a rescue inhaler (salbutamol) isn't enough when wheezing is continuous. You likely require a daily controller inhaler, like an inhaled corticosteroid, to treat airway inflammation. Please consult a doctor promptly to safely adjust your treatment plan and get your breathing under control.
