Cupping is a therapy that uses suction on the skin to increase local blood flow and may help relieve pain or muscle tightness. It can also leave temporary marks that look like bruises.

What it may help with

Cupping is commonly used for pain-related issues such as back pain, neck pain, shoulder pain, headaches, migraines, arthritis, and sometimes muscle soreness. Some people also try it for stress or other chronic symptoms, but the evidence is limited.

How it works

The suction draws the skin and nearby tissue upward, which may expand tiny blood vessels and change local circulation. Researchers still do not fully understand exactly why some people feel better after it.

Risks

Common side effects include bruising, skin discoloration, soreness, fatigue, and sometimes burns or nausea. Wet cupping has extra risks because it involves skin puncture and blood exposure.

Important note

Cupping is not a proven cure for medical conditions, and it is best done by a trained professional. If you have a bleeding disorder, skin condition, pregnancy, or a device like a pacemaker, it may not be safe.
