You may experience some discomfort during your therapy. Discontinue use and contact your healthcare provider if you feel pain. Adjusting to a lower setting may relieve some discomfort. There may be two reasons for pain associated with Milli use: tightness and angling. If you are increasing Milli’s size too fast, you may experience discomfort and Milli might hurt. Try expanding slower and over multiple sessions.  As Milli expands in a square shape, the ridges may put pressure on your urethra. If you are feeling intense pressure, you might rotate Milli to relieve discomfort.
