I have had lower abdominal and back pain for about six months. The pain is a dull ache. All female tests have come back negative. The pain does not feel like it wraps around my side. It  goes directly from front to back like something is sticking through me.
Hello! Thank you for the query. Such pain is usually caused by urinary tract infection or urinary tract stones. You may also have burning while urinating, frequent urinating. The pain can radiate to the groin. If the pain is in the lower left area, diverticulitis can be also a reason of your symptoms. This condition is strongly associated with chronic constipation. I suggest you to have some diagnostics. Please start with urinalysis and abdominal ultrasound. If you are over the age of 50, please also consider colonoscopy. Hope this will help. Regards.
