i'm 30 weeks, and i've been having a lot of back pain for the past 5 weeks or so. it's always in the same area, middle of the right side about two inches below my bra and 4 inches up from the bottom of my ribs. i asked my doctor about it about 2 check ups ago and they said it might be a knot and that it def wasn't my kidneys, but at that point i was only feeling pain some evenings and after sleeping a night it would be gone in the morning. now it hurts 24/7, from the moment i wake up til i can get myself to sleep all night and its spread around to the front of my ribcage as well. kind of feels like theres a knife stuck right through my ribs. i have a dr.'s appt in two days but im trying to figure out if i should be worried or not. is pain 24/7 normal in some pregnancies? this is my first, i'm 5'2" and baby is big for his age already.
