<s>[INST] Hello doctor, I am a 25 yr old female, married and have a 9 month old baby. I am on my midcycle now (35 days menstrual cycle). I have been experiencing cramps in my lower abdomen and back pain for the last 3 days. The cramps are mild but remain throughout the day and get worsened after doing some strenuous work. Please advise. [/INST] Hello there,The pain you are describing could be due to many reasons:1) Iflammation in your intestines2) Constipation3) Ovulation pain from ovaries (considering you are midcycle)4) Cyst in the ovaries5) Urinary tract infection upto the bladder6) Kidney stones in the ureters (pipe from kidney to bladder)To tell you the exact cause and treatment you need a thorough examination and maybe an ultrasound or CT/MRI. PLease visit a physician or a gastroenterologist who can guide you through treatment and investigations. Till then try to drink lots of water as if its a stone or constipation the symptoms will reduce.Hope this helps.Take care. </s>
