There is a tingling after I pee. Could it be a uti? No pain or discolored urine. On vacation what can I do to fix it without a doctor?

Drink lots of liquid. Wash your self with water after urination, Drink Cranberry juice or Cranberry extract tablet. And drink lots of water/liquid.
May be an infection. Even without pain or discolored urine, a 24 yo female with this symptom may still have an infection. If fever, back pain, abdominal pain, discharge, nausea, or vomiting are associated with the symptom, evaluation by a healthcare provider is recommended.
