Fluctuating loss?

Diagnosed with sshl 5 weeks ago and did 2 rounds of steroids. Hearing was 50-60 moderate dbl loss at low frequencies 250-500 and rose to normal at high frequencies. Well the hearing improved around week 4. And I was so happy. Now week 5 hearing is back to the low frequency loss with this electrical humming sound and pressure in the ear. Any tips? Any advice?
