App-based program to help chronic pain and daily activity
This study tests an eVIS tool that combines information about physical activity and pain to help people with long-lasting pain improve how pain affects daily life. You may be a good fit if you have chronic pain and can complete the program in Swedish using your own device.
FalunAges 18–67 - NCT05052541RecruitingPhase 3
Oral cannabis for long-term spine pain
This trial studies whether taking cannabis by mouth can safely reduce chronic spine pain and improve daily comfort. You may be eligible if you have long-lasting spine pain and can follow study rules about stopping or limiting other cannabis and certain other treatments.
Aurora, ColoradoAges 21–84 - NCT05058287RecruitingPhase 3
Steroid shot during low-back surgery
This trial tests whether using a steroid medicine (a steroid shot) around the time of low-back decompression surgery improves pain and recovery. It is for adults having a limited-area laminectomy, and it compares steroid use versus not using it.

Nerve block to reduce pain after kidney stone surgery
This trial tests whether an “ESP block” (a targeted local anesthetic injection near nerves) works better than standard care to control pain after percutaneous kidney stone removal. If it helps with pain, it could reduce the need for stronger pain medicines after surgery.
Knoxville, TennesseeAges 18 years+ - NCT05023005Recruiting
Strain-Counterstrain therapy for piriformis muscle pain
This trial tests a hands-on physical therapy technique called “strain-counterstrain” to reduce pain from the piriformis muscle. It may help people whose pain is coming from that specific muscle rather than the low back.
Loma Linda, CaliforniaAges 18–65 - NCT05020028RecruitingPhase 2/Phase 3
CBD to reduce knee pain from osteoarthritis
This study tests cannabidiol (CBD) to help lower pain from knee osteoarthritis. It may be an option if you have ongoing knee pain and meet age, safety, and medication guidelines.
New York, New YorkAges 40–75 - NCT04984291Recruiting
Study of shoulder replacement implants for eligible adults
This trial looks at a specific shoulder replacement implant and follow-up care for people who need a shoulder arthroplasty (shoulder replacement) for certain joint problems or fractures. You may be a candidate if you can take part in required visits and your shoulder muscles and bone are suitable.
Irvine, CaliforniaAges 20 years+ - NCT04996628Recruiting
Testing nerve pain signals to guide treatment for chronic pancreatitis pain
This study checks how your nerves respond to controlled touch and temperature tests, to help predict how well you’ll respond to procedures that relieve blockage in the main pancreatic duct. It may help doctors choose the most effective treatment for chronic pancreatitis pain.
Indianapolis, IndianaAges 18 years+ - NCT04970121RecruitingPhase 2
Duloxetine for chemotherapy nerve pain in solid tumor patients
This Phase 2 trial tests duloxetine to see if it safely reduces painful nerve damage caused by chemotherapy (especially taxanes) in people with solid tumors. If you have moderate-to-severe nerve pain and meet lab and heart-safety checks, this study may be an option.
Bengbu, AnhuiAges 18–75 - 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.
Calgary, AlbertaAges 18–80 - NCT04933149Enrolling by invitationPhase 4
Ketamine infusion for nerve pain after shoulder nerve injuries
This trial tests whether a ketamine infusion can reduce nerve-related pain after traumatic brachial plexus (shoulder/arm nerve) injuries. It specifically targets people with pain caused by nerve damage who are scheduled for surgery to repair the nerve.
Rochester, MinnesotaAges 18 years+ - NCT04929951RecruitingPhase 1
Micro fat injection to treat shoulder arthritis
This Phase 1 study tests whether a micro-fragmented fat (MFAT) injection can reduce symptoms and improve shoulder function in people with shoulder osteoarthritis. It’s early research, so the goal is mainly to see if the treatment is safe and possibly helpful.
Stanford, CaliforniaAges 25–75 - NCT04982965RecruitingEarly Phase 1
Study brain changes behind cannabis pain relief
This early study looks at how the brain may respond to cannabis to reduce long-lasting lower back pain. You may be asked to follow strict rules about cannabis, opioids, and safety checks (including MRI) to help researchers understand the brain mechanisms.
La Jolla, CaliforniaAges 21–65 - NCT04964206Recruiting
Epidural pain relief in labor and baby brain development
This trial studies how epidural pain relief during vaginal labor may affect a child’s early brain and development. It’s for first-time, term pregnancies where you plan a vaginal birth.
Beijing, Beijing MunicipalityAges 18–35 - NCT04934683Enrolling by invitationPhase 4
Medication study during major surgery to protect blood pressure
This trial tests how well an “induction agent” medication works during major surgery to help keep blood pressure stable. It may help prevent complications in people at higher risk, especially those staying overnight in the hospital.
Omaha, NebraskaAges 45 years+ - NCT04930887RecruitingPhase 2
Numbing injection in the face to ease craniofacial pain
This trial tests whether an injection of a numbing medicine (bupivacaine) guided by an endoscope can reduce craniofacial pain. It may help people with certain headache or facial pain conditions by targeting the pain area more precisely.
Stanford, CaliforniaAges 18–80 - NCT04894864RecruitingPhase 4
Opioid-free anesthesia for elective abdominal aortic aneurysm surgery
This trial studies an “opioid-free” anesthesia and pain plan during planned open surgery for an abdominal aortic aneurysm. The goal is to see whether this approach reduces surgical stress and pain compared with usual care.
Heraklion, CreteAges 40–85 - NCT04880096Recruiting
Study of people living with chronic pain
This study follows people with long-term (chronic) pain to better understand their experience. It may help researchers evaluate what support or care could be more helpful for chronic pain patients.
Clermont-Ferrand, AURAAges 18 years+ - NCT04918329Recruiting
Digestive symptom check-in study for adults
This study follows adults with long-lasting “functional” digestive symptoms as part of routine care. It may help researchers better understand these conditions and improve how they are managed.
RouenAges 18 years+ - NCT04907643Recruiting
Virtual reality program to reduce stomach-cancer pain
This trial tests whether virtual reality (VR) can improve pain and other day-to-day symptoms in people with certain gastrointestinal cancers. You’d use VR for pain relief while researchers measure how you’re feeling.
Los Angeles, CaliforniaAges 18–99 - NCT04880707RecruitingPhase 2
Pain medication options for lower wisdom tooth removal
This study compares pain-medication approaches during and after removing at least one lower impacted wisdom tooth (a tooth that’s stuck). It may help find a safer or more effective way to control dental pain after surgery.
Newark, New JerseyAges 18 years+ - NCT04860141RecruitingPhase 4
Gabapentin before wisdom tooth removal to reduce pain
This trial tests whether taking gabapentin before extracting a wisdom tooth helps with pain and comfort after the procedure. It may help people who need a third-molar removal, if they meet the safety and health requirements.
Loma Linda, CaliforniaAges 18–59 - NCT04864080Recruiting
Online study to measure brain-related signals in pain or depression
This trial uses an online study platform to look for “cognitive biomarkers,” which are measurable patterns in thinking or brain-related responses. It compares people with pain or depression to healthy controls to see how these patterns differ and could help future research or care.
Minneapolis, MinnesotaAges 18 years+ - NCT04912531Recruiting
Virtual reality and smell tools to ease surgery pain
This trial tests whether a combination of virtual reality and guided smells can reduce pain and anxiety around major heart and chest surgeries. If you’re scheduled for one of the listed operations, the study may help make recovery feel more comfortable by using sensory-based distraction.
