Thank you for the time you have taken to respond to my concerns. We will continue the investigation. Awaiting results of abd/pelv/transvag ultrasounds. Since it is the left back (flank), I am assuming this can be referred pain caused by the number of conditions you mentioned. Thank you again.
Hi
Welcome to the MedHelp forum!
There are various causes for left lower abdominal pain. I understand you have undergone several investigations. Please go through this and see if something was missed. Pain and discomfort on the lower left side of abdomen just below and to the left of navel can be due to several causes such as Crohn’s disease, colitis, diverticulitis, infection in kidney, kidney stones, adhesions, polycystic ovary in females, IBS, constipation, and an abscess in rectus abdominis muscle or psoas muscle. Since you do not have a lump or a tender hot spot, in all probability it is not a muscle. It could also be a periumbilical hernia that has got trapped resulting in small bowel obstruction or mesenteric ischemia. There is a possibility that there is a stone in the urinary system. This also causes pain that can be felt in groin and hip area.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral.
Take care!
