Worried about easily breaking bones

Ocean
Friday morning I woke up to a horrible pain in my lower ribs. Feeling around them, I notice a nice big Ole indent and Crack in my second to bottom rib. I went to the doctor, and come to find out, I broke my rib somehow. All he did was press on the spot to figure that out. I was perfectly fine Thursday, haven't had any kinds of brute trauma or anything. Haven't been coughing hard either. It's been so uncomfortable. Even breathing is strained. I can't twist or even bend over without it causing pain. Sneezing, coughing, yawning and especially my random fits of hiccups are excruciating. Has anyone else ever had something like this happen? Just randomly and unexplainably breaking a bone??
