The lower part of your prosthesis is too tight from the middle to the nose, because the prosthesis is basically vertical during the day. Because of the gravity of the earth, it will recover when you rest, and it is also because the gravity of the earth makes it docile. If this happens frequently, it is not a long-term solution. If the change is really obvious, it will make you unable to adapt and affect your life, so you should consult a doctor.
