Does Pain And Pressure In Rib Cage Require Immediate Medical Attention?

I previously wrote in about lower abdominal pain and that I had been waiting to be seen by my GYN dr at the end of the week to be re-evaluated after being treated for BV and having it reoccur (at least that s what it seems like to me), and mentioned that I had noticed my left rib sticking out. It is about an inch further out than my right, and not sure how long it has been that way. I made the appointment on Monday and was hoping that I could just wait to be seen by my Dr, but over the past 24 hours I ve developed a lot of pressure in the rib area (it didn t hurt at all when I first mentioned it) and moderate pain. Basically just enough pain to make me feel nauseous. The pain is located just under my left rib cage and hurts more toward my side than in the middle. When looking up information online about what could be causing the pain I keep coming across people saying get to a Dr immediately if you have pain there because something might rupture, but I imagine that I would be in severe pain if it was that urgent? Is it safe to wait to be seen? My appointment is in about 10 hours.
