Welcome to mamapedia!!
Listen to your doctor. If he felt it would go away on its own. Then just keep an eye on it.
My dad had something behind his ear that looked like a small black head. In three weeks time it has grown to 7mm wide and 4mm tall - it was sqamous cell carcinoma. He had it removed last Friday. All is well.
Unless you have a history of skin cancer? I would just keep an eye on it and NOT try to pop it again.
Good luck!
