Nerve blocks before chest surgery to prevent long-term pain
This study is looking at two different types of nerve blocks—one called an erector spinae block and one called thoracic epidural—given before chest surgery to see if either can help prevent long-term pain after the operation.
Kfar SabaAges 18–99 - NCT07696923Recruiting
Treating frozen shoulder with microembolization or steroid injection
This trial compares two treatments for frozen shoulder: a new procedure that blocks tiny blood vessels (TAME) and a steroid injection. You must have had shoulder pain for at least a month and be willing to do physical therapy.
TaipeiAges 18–80 - NCT07016581Enrolling by invitation
Best length for a spinal cord stimulation test
This study is testing how long a spinal cord stimulation trial should last to best diagnose whether it will help your chronic pain. It compares different trial lengths to see which one gives the most accurate result.
Baltimore, MarylandAges 18 years+ - NCT05561595Recruiting
Reducing health-related stigma through group support
This trial tests a virtual group program to help people cope with health-related stigma from conditions like obesity, cancer, HIV, diabetes, skin disease, or chronic pain. It aims to reduce internalized stigma and improve well-being.
Gainesville, FloridaAges 18 years+ - NCT07297901Enrolling by invitation
Breathing app study for migraine relief
This trial tests a smartphone-based breathing program to help reduce migraines. It uses heart rate data to guide breathing exercises tailored to you.
Phoenix, ArizonaAges 18 years+ - NCT03819738Recruiting
Brain scan during deep brain stimulation
This study checks how brain imaging works in people who already have a deep brain stimulation (DBS) device. If you have a DBS system, the study may help researchers better understand what the stimulation is doing in the brain.
Leuven, Vlaams-BrabantAges 18 years+ - NCT03876054Recruiting
Tracking outcomes after Abbott neurostimulator implantation
This study follows people long-term after they get an Abbott device implanted to help with chronic pain. It aims to learn how well the therapy works in real-world care over time.
Phoenix, ArizonaAges 18 years+ - NCT06808048Recruiting
Medical cannabis and behavior in chronic pain patients
This study looks at how medical cannabis affects thinking and behavior in people with chronic pain. It compares medical cannabis users to pain patients who don't use cannabis over a four-month period.
Minneapolis, MinnesotaAges 30–75 - NCT04028687Recruiting
Study of a hip stem used in select adult hip replacements
This trial follows people who have had a hip replacement using a specific “Taperloc Complete” stem. It is meant to monitor outcomes after surgery and see how well the stem performs over time for certain non-infectious hip problems.
Henderson, NevadaAges 18 years+ - NCT04379115Recruiting
Brain stimulation study for people with opioid addiction
This study tests a non-invasive brain stimulation approach to reduce opioid cravings in people who are actively using non-prescribed opioids while on stable methadone. It may help people feel less craving and improve recovery support.
Hinsdale, IllinoisAges 18–85 - NCT04427709RecruitingPhase 2
Testing a brain-activity measure using oxytocin and eye movements
This study tests whether a particular brain-activity signal—seen in small rhythmic eye movements—can be measured reliably. It also looks at how oxytocin (a hormone used in medical settings) affects that signal.
Winston-Salem, North CarolinaAges 18–75 - NCT04441034RecruitingPhase 4
Compare two medicines for long-term pain in real life
This trial compares two types of medicines—anti-convulsants and anti-depressants—for people with persistent pain lasting more than 3 months. It aims to find out which option works better in everyday care and for which patients.
Redwood City, CaliforniaAges 18 years+ - NCT04814082Recruiting

This study compares two designs of knee replacement implants to see how they affect walking, function, and outcomes after surgery. You may be randomly assigned to one of the implant types used for your specific, approved knee replacement.
Baltimore, MarylandAges 18–75 - NCT04933370Recruiting
Testing a brain or nerve stimulator settings approach
This study is for people who are planning to get a device implanted that delivers stimulation to the brain or nerves. The trial tests whether different stimulation settings work better, which could improve symptom control for participants.
Calgary, AlbertaAges 18–100 - NCT04938245Recruiting
Testing improvements to spinal cord stimulation with ECAPS
This study looks at a method (ECAPS) to improve how spinal cord stimulation works. It may help people who are already scheduled to have a spinal cord stimulator trial started.
Minneapolis, MinnesotaAges 22 years+ - NCT04939623RecruitingPhase 2
Probenecid to ease opioid withdrawal symptoms while tapering
This Phase 2 study tests whether probenecid can lessen discomfort from opioid withdrawal in adults who are gradually lowering their opioid pain medicine. If it works, it may make tapering feel more tolerable and safer.

Common questions
- Are there clinical trials for chronic pain?
- Yes. Clin2 currently lists 828 recruiting chronic pain studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronic pain trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a chronic pain trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
