We must respect to the letter what C. Caruso says
"If your lips become swollen, tired or stiff, wait longer before resuming the exercises. If they continue like this, do not touch them until it is comfortable. Any discomfort will increase the chances of manipulation reaching a grade and will cause a parasitic movement."
Carmine Caruso "Musical Calisthenics for Brass"
