If I post a question here with a photograph or photos, will you view them and give me an opinion?
Based on what you described, there are several possible diagnoses including sebaceous (epidermoid) cysts, pillar cysts, and folliculitis.
Since lesions have been recurring multiple times in last six months, make sure your physician evaluates them, and explain how different factors, including friction, can affect clinical outcome.
In the meantime, avoid squeezing lesions because that can trigger painful inflammatory reaction.
Yours in optimal health,
