i was told by my doctor that they were just pimples on stretch marks. She wouldn't listen to wha I had to say after she told me that, and I just dealt with it. I really truly don't think that they are pimples, they're very hard to pop, they are purple and sore, and when I do successfully pop one, all that comes out is dark blood, no puss, just blood. I get these under my armpits and on my inner thighs. They are starting to get unbearable, and at times it's hard to walk cause they're on my inner thighs. I'd really like to know what these are.
