Regarding Medrol usage. Help me out.

I had a case of tinnitus for 3 months, as per the current effect it seems like it's a venous cause due to which it happened. I visited an ent, he prescribed me a shot of renerve plus 1M, which i took. After that there's a little reduction in tinnitus(i had screeching sound, which is gone), now all i have is venous hissing/turbulent blood flow sound..) Then he has prescribed me Medrol 16mg (14 tablets for 7 days. Two tabs at night per day. I recently read about they benefits of the steroid, but it comes with so many side effects. I am not hypertensive but i easily get panicked and all when i feel any health issue.. Reading about side effect like water retention electrolytes imbalance, it really scares me.. So should I go for the course of the costicosteroid or should I ask my doctor for any alternative for this. I am really really worried should I go for it or not... Please help me out...
