How To Treat Burning Sensation During Urination Due To UTI?

I ve had 2 uti s and went to the doctors to get prescribed antibiotics. I ve had 3-4 uti like symptoms that went away after a day or two. I recently went running & I had abdominal cramping but I kept pushing myself to run because I thought it would go away..the next day, I had sharp pains while urinating. It s been going on for three days now.. all of this is less than a 9month frame. What could be going on? What should I do?,
