Unbearable itching

Hey ladies, I went to the ER last week and was diagnosed with a severe UTI. I got a shot and antibiotics. Ever since the antibiotics I have had SEVERE itching and burning in my lady parts. It feels like tiny fire ant bites non stop. Everything around me is closed and the only place that accepts my out of state Medicaid, is the ER. Would this be a reason to visit? I can’t handle the itching anymore.
