A Canadian doctor on Wednesday issued a warning about the danger of wearing low-slung jeans after three women complained of experiencing "tingly thighs" from a pinched nerve. Dr Malvinder Parmar, of the Timmins and District Hospital in Ontario, said hip-hugging jeans are not suitable for overweight women as they compress a sensory nerve which can cause discomfort, while wearing them with belts can press close to the spine.
