I AM 25 WEEKS PREGNANT AND I HAVE THIS REALLY BAD PAIN IN THE LEFT PUBIC AREA?

I HAD GONE TO THE DOCTOR ABOUT IT AND HE SAID IT IS PROBABLY OSTEITIS PUBIS (INFLAMMATION OF THE PUBIC BONE).. BUT I AM CURIOUS TO KNOW IF ANYONE ELSE HAS AN OPINION. THE PAIN STARTED OVER A WEEK AGO AND I FELT IT WHEN IT HAPPENED. IT FEELS LIKE ITS IN THE PUBIC BONE.. WHEN I MOVE MY LEFT LEG OR CARRY THINGS IT FEELS LIKE ITS ON FIRE.. EVEN WHEN I LAY DOWN I CANT LAY MY LEFT LEG FLAT ON THE BED IT HAS TO BE PROPPED UP EVEN WHILE I SLEEP. NO PAIN PILL THE DR HAS GIVEN HELPS AND IT FEELS NOTHING LIKE PELVIC PRESSURE. DOES ANYONE KNOW OR HAVE AN OPINION OF WHAT IT COULD BE AND IF IT IS RELATED TO PREGNANCY OR NOT?
