UTI hurts on the outside ??

I went to the doctor two days ago after having UTI pains that hurt so bad like all up in the pelvic area, and noticing blood in my pee. I started antibiotics and it just started to hurt and itch a little on the outside :( I haven’t found anywhere where this is listed as a symptom but is it normal?? It still hurts to use the bathroom but the internal pain is getting better
