I constantly (2+yrs) have this sharp pain anytime I sleep on my left side (stronger) or flat on my bank. It takes 20+minutes in this position to occur and then I have to roll over to my right. In that first couple of minutes it hurts to even breathe... I ve been to OB/GYN and they said it was nothing. I even had a kidney infection last year on my right side (pain was very familiar to above!) and the ER ultrasound and scans showed no stones just an infection. Since I saw a GP last fall who ran blood work, etc and she offered nothing but a urologist recommendation (after my request) - In your professional opinion should I seek a urologist or have another GP investigate (or gastro...?)? NOTE: I do have a herniated disc on my lower left side but I wouldn t assume this is causing the pain. I could be wrong...? Thank you kindly for reading :-)
