I am 26 weeks pregnant have not gained more than I should all seems well except stabbing intermittent mid back pain started about 6 weeks ago.   Chiropractor helped some but pain returns. OBGYN gave me muscle relaxers but they did not help. OBGYN says baby is fine but wants to do a sonogram of my kidneys - what is he looking for and what could be done.
DEAR SIR/MADAME CAUSES FOR STABBING AND INTERMITTENT BACK PAIN MIGHT BE FOR VARIOUS CAUSES.VAGUE LOW BACK PAIN MAY BE DUE TO PRESSURE ON THE SACROILIAC JOINT BUT IT DOES NOT Cause STABBING PAIN.THE STABBING INTERMITTENT MID BACK PAIN IS DUE TO1. GASTRITIS.2. GALL BLADDER STONES3. RENAL STONES WHICH IS VERY COMMON IN PREGNANCY.THE BEST WAY TO DIAGNOSE IS TO GET ULTRASONOGRAPHY OF KIDNEY URETER AND BLADDER.THANKS.
