Anaphylactic shock on its way?

Patient: I have itchy hives all over. Went to get it checked, they put me on prednisone and topical cream. Took my first dose of both tonight. For the past 30 min or so, my throat has been dry and feels like theres a small lump when I swallow. The hives are still there too. Should I be worried of anaphylactic schock?

Symptoms: Hives, lump when swallow

Doctor:
