I got numb spots on my thigh for both hips. At seven years, the right one is thinking about getting smaller. At three years, the left has been having a growth spurt, and I also seem to have developed something that matches the symptoms of meralgia paresthetica over the years, and more quickly over the past winter. Since loosening your clothing is supposedly one of the ways to relieve it, I'm going to guess that spending the winter days in mild compression tights did it. Too bad I need them! Anothe possible cause is, anterior THR. Ah well!
