High-dose vitamin D3 to ease chronic pain in dialysis patients
This study tests whether taking a very high dose of vitamin D3 can reduce moderate to severe chronic pain in people on hemodialysis. It may help by improving vitamin D-related pathways that could affect pain, but you must also meet specific health and testing requirements.

Checking problems in vein bypass grafts in people with recurring chest pain
This study looks at how vein bypass grafts are working over time in people who had heart bypass surgery and now have recurring angina (chest discomfort). It may help doctors better understand why symptoms come back and how the heart and grafts change.
AmsterdamAges 18–90 - NCT05767619Recruiting
Digital tool to guide care for chest pain calls
This trial tests a digital decision-support tool that helps emergency teams manage people who call for help because of chest pain. It may improve how safely and consistently chest pain is assessed and treated in the ambulance setting.

Person-centered online rehab for chronic pain on sick leave
This trial tests an early, personalized (person-centered) rehabilitation program delivered through eHealth to help people living with long-term non-cancer pain. It may help reduce pain impact and improve function while you are on sick leave from work.
GothenburgAges 18–65 - NCT05922007Recruiting

Testing pain changes during brain surgery under anesthesia
This trial studies how pain levels change during planned brain surgery while you are fully asleep, using special brain-monitoring recordings. The goal is to better understand acute pain signals during general anesthesia, which may help anesthesiologists manage pain more effectively.
ValenciaAges 18 years+ - NCT01788410Recruiting
MRI-guided freezing treatment for neck, head, and spine pain
This trial studies an MRI-guided procedure that “freezes” targeted nerves or joints to reduce pain in the head, neck, or spine. It may help if your pain comes from a joint problem or a compressed/damaged nerve and you can safely have MRI scans before and after the treatment.
Boston, MassachusettsAges 18 years+ - NCT05981261Recruiting
Experimental pain study in Parkinson's and healthy adults
This study looks at how people with Parkinson’s, treated either with levodopa or deep brain stimulation (DBS), and healthy volunteers experience pain. The goal is to understand how Parkinson’s treatments affect pain perception.
AarhusAges Any age - NCT04189965Recruiting
Study of long-term memory of pain in healthy adults
This study looks at how people remember pain over time. It enrolls healthy adults so researchers can better understand the long-term effects of painful experiences.
BronAges 18–50 - NCT06012552RecruitingPhase 2
Tianeptine for COVID-19 brain fog
This study tests whether the medication tianeptine can improve brain fog and thinking problems that persist after COVID-19. It may help if you are 18 or older, have had COVID-19, and have noticed new memory or concentration issues.
WarsawAges 18 years+ - NCT06029764Recruiting
Extended fusion for spinal disc vacuum signs
This trial tests a surgery that fuses one extra spinal disc to treat a 'vacuum sign' (air pockets in the disc) that hasn't caused symptoms yet. It aims to prevent future problems in people with lumbar disc disease who need fusion surgery.
Beijing, Beijing MunicipalityAges 18–60 - NCT05963451Recruiting
Testing treatments for long-term low back pain from facet joints
This study focuses on people with long-lasting low back pain that likely comes from the small “facet” joints in the lower spine. It aims to better understand brain, psychological, and biology changes to help optimize treatment for this type of back pain.
Sherbrooke, QuebecAges 18–75 - NCT04873687Recruiting
ECP treatment for stable angina while waiting for heart care
This trial studies whether ECP (a non-surgical treatment that improves blood flow to the heart) can reduce symptoms in people with stable angina who may need or are waiting for heart bypass surgery, or are being managed with medicines instead. It may help you feel better and need less urgent care—if you meet the study’s medical and personal requirements.
Bandung, West JavaAges 18 years+ - NCT02257723Recruiting
Testing combined Korean herbal and therapy for hospitalized spine or joint pain
This trial studies whether a combined complementary treatment approach helps people who are hospitalized for spine or joint problems. It may help reduce the types of pain that come from those areas.
Seoul, Gangnam-GuAges Any age - NCT04606459Recruiting
Device trial for hard-to-treat heart chest pain from small vessels
This trial tests whether a small pressure-reducing device placed in a heart vein (the coronary sinus) can reduce symptoms in people with ongoing chest pain from tiny blood vessel problems. It is for angina that has not improved despite standard heart medicines, and only if special heart tests show reversible reduced blood flow.
Mainz, Rhineland-PalatinateAges 18–85 - NCT06058182Recruiting
Rna biomarkers for heart attack patients
This study looks at RNA markers in the blood of people having their first heart attack to see if they can predict recovery. If you are scheduled for a procedure to open blocked arteries, you may be able to join.
Milan, MilanAges 18 years+ - NCT06083558Recruiting
Pain and nausea after gallbladder surgery

Kidney stone pain treatment after ER discharge
This study compares an anti-inflammatory pain medicine (NSAID) given by mouth versus acetaminophen (paracetamol) or placebo after you leave the emergency room for a “renal colic” (kidney stone pain). It looks at whether the NSAID helps control pain better and whether it’s safe for people with uncomplicated kidney stone pain.
MonastirAges 18 years+ - NCT03862365Recruiting
Study genetics in people with nerve pain
This study looks at genetic differences in people being checked for a common type of nerve problem called distal symmetric polyneuropathy (nerve damage that usually affects the hands and feet). By understanding genetics, researchers hope to learn more about why neuropathic (nerve) pain happens and how it may differ between people.
