Help!!! Cough, peeing pants, general misery

Amanda
For almost 3 weeks I've had this really annoying drainage in the back of my throat, causing me to constantly have a tickle in my throat and constantly cough. Every time I cough, I pee. No matter how many times I go to the bathroom, I STILL pee. I broke down and bought depends today. On top of it, trying to jump out of bed to get to the bathroom while coughing, I've pulled a muscle (I think??) In the side of my abdomen so now there's sharp pain every cough. The dr office said robutussin was safe and also Claritin for the drainage. But nothings helping at all. Anyone had this? Any ideas? I'm so frustrated by this cycle and exhausted...😧 sorry for the long vent
