52 year old woman, period has been spasmotic for last 12 month, yesterday experienced such severe lower back pain on right side and then it would move across lower stomach, the only way I can describe the pain is the same as baby contraction pain, the intensity of the pain also made me vomit a number of times, pain lasted about 5 hours but I did end up taking some panadine forte which my husband had, still feel a few twinges of pain in my lower back right side today and a bit queasy so not sure if related to some sort of gastro virus or some sort of menapause melt down!
