Too-tight pants could result not only in unsightly muffin top and rippling fabric in the crotch area, but also in a nerve condition called meralgia paresthetica, now seen in increasing numbers among young fit women.
Coupled with stiletto heels, the pressure these jeans put on the femoral cutaneous nerve that runs through the thigh can cause tingling and burning through the leg.
They don't quantify how tight the pants would have to be to achieve this result, but the condition is normally seen in construction workers, pregnant women, and obese people (oh, the irony), not young gym bunnies. Meralgia paresthetica has become known as "tingly thigh syndrome." Explains sufferer Parmeeta Ghoman:
“It felt really strange — it felt like my leg had gone to sleep.”
Luckily the problem is easily remedied in young, fit ladies. All they have to do is wear looser pants and the tingling should subside with no permanent damage. “It is a pure sensory nerve — it doesn’t go to muscles or provide strength. Anything that is tight around there could potentially compress the nerve that goes there,” explains a doctor. Well, this does make the strongest case we've seen for jeggings. And pantslessness, for that matter. But more than those things, the rare pants that allow air between fabric and skin, which we will unflaggingly support.
