Painful air bubbles in urinary track normal?

Had a uti treated with cipro, two days later urine flow stopped rushed to the ER. Cath. Drained me, they sent me home, later that night had to go back cuz I couldn't pee they put another catheter in me. Removed it inserted a large one flushed me, removed it inserted another sent me home in agonizing pain. Next morning back to the ER. Removed that one put a smaller one in me, next day seen a specialist. Removed it, peed in a cup and sent home...... No answer to why any of it happened. Now... My legs have been hurting and I feel I have painful air bubbles randomly coming out of my urinary track. I thought I would heal... Is this normal?
