I keep rubbing Algesal Cream into them, which I find is very good for aches and pains, and a couple of Co-codamol. Thanks sqad, and best wishes to your mum Chuck.
Definitely - I had it on both sides for over three months once, and was so scared it would never go away. I spent a fortune on heat pads, and had them plastered all over my bottom (!) and thighs, just so I could carry on going to work. I still almost fell over every time I had to get up from my desk though, the pain would just make my legs give way :(
If it is sciatica, hope it goes away for you soon.
If you lie on your back on the floor with the backs of you lower legs resting on a chair it gives some relief from the pain. But only for a short while
