In a four-week trial, researchers prescribed participants with a course of Botox or saline injections. At the end of the study, the 13 women who received the treatment reported lesser pain or said that it had subsided completely.
“The botulinum toxin injections were incredibly effective in decreasing pain levels, as well as patients’ use of pain medications, including opioids,” the study’s lead author and gynaecologist Dr Pamela Stratton explained.
“Many of the women in our study reported that the pain had a profound effect on their quality of life, and this treatment may be able to help them get their lives back.”
More research is needed to confirm these results, although it does look promising for the 176 million people who currently suffer from the disease worldwide – in particular, those with chronic pelvic pain.
“These findings suggest that pelvic floor muscle spasm may be experienced by women with endometriosis and contribute to pain persisting after standard treatment,” Lancaster University biomedical sciences graduate, Kate Anderton added.
