I have been to the GP over this last summer btw, and plan to go back soon btw. I have lower back pain which has gradually been getting worse for a few years. I am usually OK sitting (but sometimes get hip pains after very prolonged periods of sitting, eg. on car journey) or walking or exercising, but have problems standing still, or with the stop/start motion of pottering round the shops. It's also uncomfortable standing over sink/wash basin for more than a few minutes. Does any of this ring bells with anyone?
On bad days I just take some paracetamol, which doesn't always help much, or if I'm at home use ibuprofen gel (GP recommended the gel). GP reckoned it was back spasms btw.
