Horrible vaginal pain

Recently I had 2 nights (3 hours in length) of extreme pain lying in bed . I’ve had numerous UTIs but this was much worse. I felt as though I was sitting on a bed of hot, broken glass-naked! Thought I would lose my mind. The nurse practitioner at my nursing home prescribed a 3day antibiotic which stopped it.
Has anyone experienced such a situation? Haven’t been able to get to my urogynecologist as yet.
