<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 34 year old female, 56 158lbs. I have been experiencing twitching almost like fetal movement for the past month. In addition to the movement I have had lower back pain and bloating. I have had my period every month so do not think that I am pregnant.  <response>: Hello! Welcome to Chat Doctor. This can be due to infection causing inflammation of bowel pain. But as you have mentioned lower back pain, it is more likely due to a stone in urinary tract. This stone causes obstruction to urine outflow, so smooth muscles in urinary tract contract excessively to overcome this obstruction so is the pain. Many such patients come to my clinic to whom I advise ultrasound abdomen pelvis, X-ray PUB, urine routine, renal function tests CBC. For temporary pain relief, smooth muscle relaxants like Chat Doctor. Definitive treatment is done accordingly. Hope this helps. Wish you healthy life. Thanks. Regards.
