I have a severe lower backache on the right hand side. I only get this during the night or the early hours. It feels like I have been kicked in the kidneys. I have had this problem for two weeks now.

The area you refer to is associated with the liver, although pain from there would also tend to extend up and around to the front of the torso following a path under the right hand side of the ribcage.

More likely is a strain that is worse with rest, as most strains are.

I'd initially try some Atrogel^® applied morning, noon and night for a week or two.

If you've no improvement by then, I'd ask the doctor about the pain.

Best wishes
