Visit 1
-Inclusion visit, signature of informed consent form, clinical examination and fill questionnaires.
For women of childbearing age a pregnancy test will be performed.The pain will be measured by a numerical scale.

The output of the hospital patient (CPC / CETD) after each treatment will be authorized by the investigator.
Wash-out period: 5 weeks.
Phone call 1 (Day 1):
