I have noticed that over the last several weeks I have developed small red bumps on my chest. They look like pimples at first but when I squeeze them I only get a small amount of clear fluid out of them. They feel as if they have a pinpoint size hard center. After squeezing them instead of going away they become red and inflammed. I am 60 years old and have had acne all my life but these appear to be something different. They do not itch and are only tender and red after I have squeezed them. Any ideas?
