What Causes Blood In Urine After Coughing, With Pain Improving But Persisting For A Week?

Question: I coughed while urinating for the first time in the morning. My urine was normal until the cough which then caused me to bleed. Its been a week now and I still have a little fresh blood come out in the mornings. By mid day its stopped...until morning again. I can feel the tear internally about mid to top in the tract. Pain for the first day was a 10 while urinating. Now its down to a 4. Is there something I can do to make it heal faster? Do I need to stop drinking sodas for now and only water? I have not had sex since all of this, in fear it would make something worse. My biggest fear is it getting an infection.
