It has been observed that the tight-fitting clothing reduces the freedom of movement in the legs, which causes some discomfort in the lower back because you cannot walk properly.
Besides the above tight clothing can cause nerve problems as paraesthetica meralgia, which is a syndrome in which mainly tingling and numbness in the thigh occurs.
The veins of the legs are also affected by excessive pressure of this clothing generating insufficient venous return, so the blood stays these limbs and deforms the veins.
In addition, this type of clothing can cause problems in the genital area, increasing the likelihood of vaginal or urinary tract infections because there is no proper ventilation in this area and therefore increases natural moisture and increase the proliferation of microorganisms.@SSalud_mx y @_MJuan_
