I have bumps on my chest . They are oval or circular in shape and I only have a few. I thought that it was a pityriasis rosea but I didn t have a herald patch and it hasn t spread rapidly. I am anxious to figure out what it is becuase it has been bugging me for the few weeks I ve had it for. My father tells me that it s just normal and it will go away on it s own, he has also told me that he has some too. My skin is fairly clear and I don t get acne except for maybe one or two pimples . I am very worried that it could be serious and could spread to my face or my arms.
