Two-Thirds of Women with Chronic Pelvic Pain and Fibromyalgia Have Tried CBD, with 81% Reporting Pain Improvement
Among 1,382 women with chronic pelvic pain and fibromyalgia, two-thirds had tried CBD, with 81% of current users reporting pain improvement and many substituting CBD for other medications.
Quick Facts
What This Study Found
36.3% never used CBD, 29.2% past users, 34.5% current users. Among current users, 80.9% reported pain improvement. Those with pain improvement also reported better sleep, anxiety, depression, fatigue, and overall health. Many substituted CBD for at least one other medication. About half reported side effects, most minor (drowsiness 29% most common).
Key Numbers
1,382 participants. 34.5% current CBD users, 29.2% past users, 36.3% never used. Pain improvement: 80.9% of current users. Improved sleep, anxiety, depression, fatigue, overall health correlated with pain improvement. Side effects: ~50%, mostly minor (drowsiness 29%).
How They Did This
Cross-sectional secondary analysis of online survey distributed through the National Fibromyalgia Association (April-May 2020). Limited to participants with concurrent chronic pelvic pain diagnoses. 1,382 included participants.
Why This Research Matters
Chronic pelvic pain and fibromyalgia are notoriously difficult to treat. The high CBD use rate and self-reported symptom improvement, along with medication substitution, suggest patients are finding relief that conventional treatments may not provide — though placebo effects cannot be ruled out.
The Bigger Picture
The medication substitution finding is significant — if CBD allows patients to reduce use of opioids or other high-risk medications, it could represent meaningful harm reduction, even if its mechanisms are not fully understood.
What This Study Doesn't Tell Us
Self-reported outcomes susceptible to placebo and expectancy effects. Survey distributed through patient advocacy organization (selection bias). No control group. Cross-sectional design cannot establish causation. 2020 survey may not reflect current landscape.
Questions This Raises
- ?What medications are patients substituting CBD for?
- ?Would a controlled trial confirm the self-reported pain improvement?

What do these levels mean? →Frequently Asked Questions
Does CBD help with chronic pelvic pain?
In this survey of 1,382 women with chronic pelvic pain and fibromyalgia, 81% of current CBD users reported pain improvement. Those who improved also reported better sleep, mood, and energy. However, this is self-reported and not from a controlled trial.
Can CBD replace other pain medications?
Many participants reported substituting CBD for at least one other medication. While promising for harm reduction, this survey cannot determine if CBD is as effective as the medications it replaced. Patients should consult their doctors before making substitutions.
