Deviated Septum. For immediate surgery?

I have shortness of breath and sudden palpitations for which I thought I might have problem in my heart or lungs. So went for ECG, spirometry also x-ray of heart around 1.5-2months ago. But all the reports were normal. Then recently I came to know I have deviated septum, after evaluating me my ENT doctor said I have to undergo a surgery (Septoplasty I guess). But it's not possible due to this pandemic situation for immediate operation. So he gave me flutiflo n Montex. But since 1 weeks I am having a bit severe shortness of breath and my pulse rate increases for few minutes. When I try breathing hard it feels I might have an heart attack. What should I do pleàse suggest? Is these symptoms normal or should I go for immediate surgery? Please tell me some of the things I can do as of now
