Allergy to the nail? Spider veins? Stretch marks?

Edit Post

I noticed them since a few months ago and wondering what they are. No strange feeling when touched and not buldging. The ones on the femurs appeared from time to time since the lenghtening period whenever hot pads had been applied  but then disapeared after a while.
Now that i use hot pads two times a day, is it the result of them? But if so why are they also on the hip areas. I never apply heat to those areas.
