I tend to get a day or two of bad cramping each month but can cope with some painkillers and a heat pad. I'm on day 2 of my period this month and woke up in absolute agony, from mid back to mid thigh. Thought I was going vomit, had to crawl to bathroom as I couldn't stand. Spent about an hour just writhing on my bed moaning, haven't experienced pain like this since childbirth. At one point my face and legs went tingly and numb. I'm 43, no signs of peri yet - could it be that?? It's starting to pass now, still alot of pain but I can stand and walk around. What's this about??
