Hello,
What you are describing may very well be a sebaceous cyst (otherwise known as a pilar cyst or a wen). The fluid filled cyst is degenerated keratin and sebum, which have been trapped inside. These cysts can sometimes get infected, and should not be pinched or squeezed.
Once infected, the sebaceous cyst can enlarge with fluid. If squeezed or pinched, the fluid within may cause the spread of the infected fluid to cause the formation of other cysts to the area.
I'm glad that you are seeing your physician for evaluation. He can detect if an infection is present, and whether or not this needs to be removed. He may also refer you to a dermatologist if he hasn't already.
