Comparing two pain relief methods for gallbladder surgery
This study compares two ways of giving pain relief after gallbladder removal surgery: an injection of numbing medicine around the belly muscles (guided by ultrasound) versus a simple injection into the skin near the surgery cuts. The goal is to see which method provides better pain control and comfort after surgery.

Pain relief for new muscle and joint injuries
This trial compares two common treatments for new muscle or joint pain: an over-the-counter pain reliever (Tylenol and ibuprofen) versus an oral steroid (a stronger anti-inflammatory medication). The goal is to see which option works better for short-term pain and recovery.
Buffalo, New YorkAges 18 years+ - NCT06391242RecruitingPhase 3
Comparing radiation treatments for painful bone metastases
This trial compares two types of radiation therapy—standard palliative radiation and a more targeted high-dose treatment (SBRT)—to see which better relieves pain from bone metastases that have spread outside the spine. It is for people with solid tumors who have a painful bone spot and are expected to live at least 6 months.
Calgary, AlbertaAges 18 years+ - NCT07856433Recruiting
Biofeedback training for forward head posture and neck pain
This study compares two types of biofeedback training (using pressure or visual cues) to help correct forward head posture and reduce neck pain, disability, and improve neck movement. If you have neck pain and a forward head posture, this therapy might help you.
Islamabad, FederalAges 19–44 - NCT07571837Recruiting
Nano-medication to reduce inflammation after root canal retreat
This study tests a special nano-sized (extremely tiny) medication placed inside a tooth after a previous root canal treatment failed. The goal is to reduce inflammation and swelling in the bone around the tooth's tip so it can heal better.
Cairo, Nasr CityAges 20–40 - NCT07441421Recruiting
Improved pain relief for brain tumor surgery
This study tests a combination of pain-relief methods given before, during, and after brain surgery to see if they better control pain and help you recover with fewer side effects. It's for adults having surgery to remove a brain tumor.
BeijingAges 18–65 - NCT06997016Enrolling by invitationPhase 4
Recovery program for living donor kidney transplant
This trial tests a special recovery program (ERAS) for people who get a kidney from a living donor. The program aims to help you heal faster and feel better after surgery.
Fort Worth, TexasAges 18 years+ - NCT04209504Recruiting
Nerve block study for one-sided breathing muscle weakness after shoulder surgery
This trial tests whether a longer-lasting nerve block during shoulder surgery can better manage pain and affect one-sided diaphragm (breathing muscle) weakness. It may help people having planned (first-time) shoulder surgery who are able to follow study pain-checks.
Durham, North CarolinaAges 18–80 - NCT07040397Recruiting
Massage therapy study for lower back pain
This study tests whether an electronic approach to massage therapy can help relieve lower back pain. It may be an option if you have persistent lower back pain and haven't used pain medications recently.
Rochester, MinnesotaAges 18 years+ - NCT03371121Recruiting
AMIC cartilage repair for ankle cartilage damage in adults
This trial studies outcomes after a specific ankle cartilage repair surgery called AMIC. It looks at clinical results and imaging (pictures) after surgery to see how well the treatment works.
MilanAges 18–65 - NCT03625011RecruitingPhase 4
Gabapentin before tonsil surgery to reduce pain
This trial tests whether giving gabapentin before pediatric tonsil (and possibly adenoid) removal can reduce postoperative pain. It may help children feel more comfortable after surgery while still being safe to use in the right patients.
Atlanta, GeorgiaAges 3–18 - NCT03949400Recruiting
