Since summer i have been getting this very itchy feeling on the backs of my thighs. Nowhere else, just there. There is no rash, no flaking skin, no bumps....just very itchy. And if I scratch it it hurts. I thought it was an allergy so i switched laundry detergents, removed my sheepskin seat cover from my truck(allergic to wool), started using baby powder but her its spring and nothing is working. But i do notice its worse when i take a shower. Should i be concerned?
