I'm 43 and in August I had back pain for 3 weels, it was worst when I was on holiday for a week and started just before my period and got worse about a week later. I went to the gp but by then most of the pain had gone and not really much they could say or do. I have had intermittent back pain over the years but not really anything that has lasted or been a real problem until now. I came on my period last week and felt a niggle in my back. Two days ago it got worse and yesterday I woke up in pain and literally could not do anything all day. Standing is painful, sitting is painful and bending over is impossible. I have heat patches and taking naproxen which seems to have helped a bit. It feels a bit better today but I have so much to do and can't do it. Has anyone experienced this? Could it be peri menopause related as I'm getting quite a lot of symptoms of peri anyway and it has come on the same time as my period on August (last period I was fine). I just worry that this is something which is going to keep coming back. I started doing pilates a couple of months ago to help strengthen my back and I am overweight but day to day I'm fine. My periods over the last year have gone a bit weird and I've had scans and blood tests to rule out any serious conditions due to family history. They came back clear and my last smear a few weeks ago was clear. Anyone have any thoughts or has this happened to you?
