hi, I have a group of about 4-5 raised painless bumps on my chin they look like scares from having pimles but are not. When i hold the skin tort they become a yellowish colour and if i am able to squese on it is like the insidewof a black head but can become inflamed. I hate having them and don't know how to make them go. i've tryed pimple creams face wash scrubs and more but nothing seems to work. any answers please help???
