When you have pain it is important to seek medical advice as to what is causing that pain and to follow the doctor’s advice. It might be stemming from a serious cause.
Even if it is not, you may still experience occasional everyday sort of pain in your lower back, hip, leg, arm etc.
My neighbour advices the following which helps to relieve pain. If you have pain in your arm or leg or lower back, rub the area with firm downward strokes with some skin cream. (I would then wipe off the skin cream with tissue or paper towel), then apply a heat producing product such as Dencorub. This is a brand name for a common pain relieving cream. I do not have shares in this or in any other company. Any similar product will do. It is worth a try!
