I have been taking penicillin for about 9 days now, I only have about a day left of taking it for what was an infection in my gums. However over these past couple hours I have been having a constant urge to relieve my bladder and when I do, immediately after urinating it burns and there is a very light amount of blood. When I googled this, I found it was mostly likely a symptom of Penicillin. My question is should I stop taking it? And should I go see a doctor?
