Whooshing sound after a flight. Ear?

I was having constant dizziness for almost two months after I Covid in Jan 2023.. Intially my eyes also rapidly moved from left to right for a few moments on one day when the dizziness was acute.. BP was fluctuating.. was on the higher side..then the lightheaded changed after 2 months and I would get dizzy when I slept on my right side or turned towards by right side.. ENT doc diagnosed it as BVPP vertigo after examination and put me onto Vertin 8mg thrice a day for 30 days. The symptoms had come under control but I took a flight two days ago and ever since I landed I can hear a mild whooshing sound in left ear and the vertigo symptoms are showing up again. Will it stabilise and what do I to cure the whooshing sound in my left ear? I also had a fungal ear infection in Jan 2023 and the ENT doc gave me ciplox and Cepodem.
