When cryotherapy is applied for physiotherapeutic or aesthetic purposes , there is no secretion of any kind. However, in cases in which it is applied for the elimination of lesions in organic tissues such as cervical cryotherapy for the cervix, or in other procedures in organs such as the prostate or kidneys, it is quite common that the following days a watery liquid that may be accompanied by blood is secreted from the rectum, urethra or vagina.
This is nothing more than dead organic tissue and fluid produced by the body when regenerating such lost tissue. It is considered a side effect and is not always present. However, it is not considered a serious abnormality. On the contrary, it is a good symptom that it is naturally expelled from the body.
The only risk with this liquid is when cryotherapy is performed at the level of the thoracic region, since it can surround the lungs and alter their functioning, although it is very uncommon to see the presence of this liquid in this area. Although as a precaution your specialist can perform a chest x-ray to rule out its existence.
