I would like to know what is this I have been having for 2 years.

When I am standing straight and look down, I can see protruding from my skin lumps above my thighs. They seem larger and more in quantity when I take my hands, put them on my waist, slide my fingers and rub with a force down the crease between my thigh and groin.

Do anyone who what is my condition caused by? and how can they be diminished? I am 20 years of age.

Thanks in advance.
