I'm 19 years old and a few months ago, a strange itching would always appear on my thighs or legs and everytime I scratched, strange red little dots would appear on the same place, but not like swollen as in allergy, they are inside my skin and are really red, lasting for 4 or 5 days. They don't hurt, but it's definitely something new and I'm kinda worried about it since I searched and I haven't found anything. Here follow some pictures, first one being from last week and second one from today, just a few minutes ago. 1 - https://photos-4.dropbox.com/t/2/AAA0UCJM7JaoHcquLejOKMHH3sCgZRR-wK2jaTB3L-Uz9A/12/247225416/jpeg/32x32/1/_/1/2/20151128_132132.jpg/EKLE1t8BGOIIIAIoAg/n7RakC8rHXQDzeCd6xvyJ2kuTx9JNWeXi0djy8ggXWo?size=1024x768&size_mode=3
