I'm suffering for heavy lower abdominal pain since last 6 months. It starts one or two days before the period starts and continues till one week or some times ten to twelve days. Pain felt like something heavy in lower abdomen and it's like cramp even when walking or any movement of body. Even after taking 3-4 pain killers in a day, there's no improve in pain. At this condition, please suggest me  what type of treatment or medication is needed and let me know about the disease probably. Thank you
