Cauliflower Ears, Swelling After Piercing?

At one month, any swelling should have resolved. Your history does sound suspicious for a perichondritis, infection of the cartilage of the ear. This can be serious and disfiguring without proper treatment. You should seek a consultation with an Otolaryngologist to determine how to proceed.

My general recommendation for piercing of the cartilaginous parts of the ear is "don't do it".  The cartilaginous pinna (ear) is relatively less vascular in its interior and therefore less tolerant of piercings.  If you still have swelling after one month, you may want to consider removing the piercing, but its probably best to see a Facial Plastic Surgeon or Plastic Surgeon in consultation to evaluate for infection.

You should see a doctor immediately. You probably have an infection of the cartilage. Do not mess around waiting. You also might be allergic to the metal used. Nickle is a common alloy used in earrings  and can cause your type of reaction. Nickle can be mixed with gold, and silver
