This trial tests whether high-intensity laser therapy can reduce long-lasting neck pain and improve daily function. It may help people whose neck pain has lasted at least 3 months and who meet specific pain and disability scores.
Santiago, Las CondesAges 18 years+ - NCT06271447Recruiting
Pain questionnaire study for chronic low back pain
This study looks at how well pain questionnaires measure changes in chronic low back pain over time. If you have had long-term low back pain, researchers want to see if these surveys can accurately detect meaningful improvements.
Istanbul, None SelectedAges 18–65 - NCT06388590Recruiting
Acupuncture for chronic pelvic pain
This trial tests whether acupuncture can help relieve long-term pelvic pain. It is for women who are part of the military community and have not had endometriosis found during a laparoscopy.
Nellis Air Force Base, NevadaAges 21–65 - NCT06533917Recruiting
Spinal cord stimulation for chronic abdominal pain
This trial tests whether spinal cord stimulation (a device that sends mild electrical pulses to nerves in your spine) can reduce chronic abdominal pain that hasn't improved with standard care. It might be an option if you've tried medications or nerve blocks without success.
LeedsAges 18–130 - NCT06874816Recruiting
Neck pain, teeth grinding, and mouth behaviors study
This trial looks at how chronic neck pain is linked to teeth grinding (bruxism) and other mouth-related habits. It aims to see if muscle thickness in your jaw is related to your neck pain.
Istanbul, BeylikdüzüAges 18–65 - NCT07021586Recruiting
Tongue pressure in adults with chronic neck pain
This study looks at how tongue pressure might be related to chronic neck pain in people aged 50 to 65. If you have ongoing neck pain, it could help researchers understand how your muscles work.
TaipeiAges 50–65 - NCT07187219Recruiting
TMS for nerve pain in cancer patients
This trial tests if repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation, can reduce chronic nerve pain caused by cancer or its treatment. It may help patients who have not found relief from standard pain medications.
Saint-EtienneAges 18–85 - NCT02991625Enrolling by invitation
Brain scan study to find markers for chronic back pain
This study uses brain imaging (MRI scans) to look for “biomarkers” (measurable signs) that may relate to chronic low back pain. It compares people with long-lasting back pain to healthy volunteers to understand what brain patterns are linked to pain.
Halifax, Nova ScotiaAges 18–75 - NCT07544108Recruiting
Understanding What Affects Neck Pain Recovery
This study helps researchers understand which patients with long-term neck pain recover better and why. By learning more about your neck pain and how it affects your daily life, the study may help doctors predict outcomes and improve treatment.
Kütahya, KütahyaAges 18–65 - NCT07352384Enrolling by invitation
Brain stimulation for chronic face and mouth pain
This trial tests if a non-invasive brain stimulation technique (called TMS or tDCS) can help reduce long-lasting pain in the face, jaw, or mouth. It's for people who have tried other treatments without enough relief.
Almada, Setúbal DistrictAges 18–75 - NCT06957639Enrolling by invitation

This study tests whether virtual reality (VR) can help reduce chronic muscle pain that is not caused by cancer. If you have fibromyalgia or similar long-lasting muscle pain, you may be able to join.
Udine, Friuli Venezia GiuliaAges 18–50 - NCT05505188Recruiting
Predicting long-term pain after head and neck radiotherapy
This study looks for ways to predict and improve pain you may have months after radiotherapy for first head and neck cancer. It may help doctors better anticipate pain and support patients during recovery.
CaenAges 18 years+ - NCT07368920Recruiting
TENS for low back pain in adults
This study tests if a non-invasive device called TENS (which uses gentle electrical pulses) can help relieve low back pain that comes from muscle knots or tight bands. The device is applied to the skin over the painful area.
Xi'an, ShaanxiAges 18–65 - NCT07002944Recruiting
Testing nerve treatment for shoulder pain after mastectomy
This study compares two types of pulsed radiofrequency (a minimally invasive treatment using radio waves) to see which better relieves shoulder pain in women who have had a mastectomy. It's for women who still have pain despite taking a high dose of tramadol.
CairoAges 18–65 - NCT05152264Recruiting

Common questions
- Are there clinical trials for chronic pain?
- Yes. Clin2 currently lists 829 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.
