If your ear still feels uncomfortable or has a lump after being pricked for more than a month, I suggest you consult a doctor or a professional ear piercer immediately. Hard lumps may be caused by infection or scar formation and need to be handled by professionally trained people. When waiting for medical treatment, you can wash it with a mixture of warm water and salt to avoid direct contact with your ears. In addition, don't take off the earrings forcibly, which may aggravate the symptoms.
