Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial studied capsaicin-evoked pain in people with CRPS — since it's now completed, can you tell me what the researchers found, and whether those findings have changed how you approach diagnosing or treating my condition?
2The study used capsaicin to deliberately trigger pain responses — what does that actually involve, and would a test like that be uncomfortable or risky for someone with CRPS who may already have heightened sensitivity?
3Since this trial is listed as 'Phase NA,' it sounds like it was more of a research or observation study rather than testing a treatment — does that mean it wasn't designed to directly help participants, and how would that affect whether something like this is worth considering?
4Are there any follow-up studies or treatment trials that grew out of this capsaicin research that might be more relevant to my current situation with CRPS?
5Given that this trial is completed, is the kind of information it gathered about pain mechanisms something that's already influencing the treatment options you're recommending for me?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
