I have had what appears to look like a whitehead pimple on my ball sack. However, when I attempted to pop it nothing happened. It seems it is deeply embedded. I proceeded to break the skin and with very hard squeezing it surfaced and I was able to use tweezers to pull it out. To my surprise, it was not puss. It was more like a solid seed looking thing. Half of the seed (we will call it for lack of better term) was white and the other half a brownish color. Was this a cyst? Should I be worried. It really just looks like a pimple but apparently is not a pimple. I have one more very small in size on my sack as well. Please advise.
