Most require a confirmed diagnosis, often with X-rays or blood tests, and set rules for pain medicines during the study.
Matching a page like this one never means you qualify. Each research team decides eligibility at screening.
Questions
Can I keep taking my pain medicine?
Some studies allow it, some require a washout period first. The study team will explain the rules before you agree to anything.
