Thanks for talking on the phone.
As discussed you may wait till the weekend. If the symptoms do not resolve, you may need an STD screeening.
Past history or family history of passing stones may also cause these symptoms.
A urinary tract infection, as a rule, warrants a urine culture for evaluation (with a routine urine analysis). A urine culture test substantiates the infection, gives you the best antibiotic to treat and eradicate the infection, and prevent its recurrence.
Treating a UTI without a culture test is like going into the sea without navigation help.
You may go to your GP or to a walk-in clinic for the urine culture to properly manage it.
Following measures would be helpful, meanwhile;
1) Drinking plenty of fluids and water
2) Cranberry extract capsule.
3) Avoiding alcohol drinks and caffeine drinks
4) Azo/Pyridium for urinary burning/pain (it is without the prescription and is a urinary analgesic).
