Cream for Protruding Hemorrhoids

Numbing medicine for pain after hemorrhoid surgery
This trial tests a long-acting numbing medicine called liposomal bupivacaine to see if it reduces pain after hemorrhoid surgery better than standard care. It may be an option for people who are otherwise healthy and scheduled for this surgery.

Botox before hemorrhoid surgery to reduce pain after surgery
This trial tests whether injecting botulinum toxin (Botox) into the anal muscle before hemorrhoid removal surgery can lower pain after the operation. It is for people with advanced hemorrhoids that have not gotten better with other treatments and who are already planning to have surgery.

Lidocaine vs Nitroglycerin for Pain After Hemorrhoid Surgery
This study compares a lidocaine ointment versus a nitroglycerin (GTN) ointment for pain relief after hemorrhoid removal surgery. It aims to see which works better for patients with advanced hemorrhoids.

Pain after hemorrhoid surgery: standard vs bipolar sealer
This study compares two ways of removing hemorrhoids during surgery: one uses a standard electric tool, the other uses a special device (Caiman®) that seals blood vessels. It aims to see which method causes less pain after the operation.
Sabadell, BarcelonaAges 18–65 - NCT06798155Recruiting
Music to prevent pain after anal surgery
This study tests whether listening to a specific set of music before and after surgery for hemorrhoids, fistula, or anal fissure can help reduce pain. You would use a phone or tablet app to listen to short music sessions.

Methylene blue for pain after hemorrhoid surgery

Common questions
- Are there clinical trials for hemorrhoid pain?
- Yes. Clin2 currently lists 7 recruiting hemorrhoid 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 hemorrhoid 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 hemorrhoid 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.
