Hi! About 2 To 4 Times A Year I Get

Hi! About 2 to 4 times a year I get an outbreak on my face. Starts on the jaw line and has the appearance of pimples but if you pop them they ooze clear liquid and itch like crazy. Then over the next day or 2 I get more. They do not go away without action. The ONLY action that works is anit-biotics, which gets rid of them quickly. I have seen a few docotors about this and no-one really knows what it is. The closest we got to a diagnosis was one doctor who thought it was a type of varicella. Anyway, my doctor gives me a 2 day course and it all clears up. Wihtout ant-biotics it doesn't go away. Can you please tell me this is??
