- The most basic type of cupping is known as dry cupping and involves nothing more than cups and suction. Often the cups have suction mechanisms built-in, allowing the physician to apply them without the need for external aid.
- The second type of cupping is a variety of dry cupping called fire cupping. In this variety, fire is used to heat the interior of the cup to lower the density of the air inside. As the air cools, it creates negative pressure, providing suction without the need for valves or pumps.
- The third type of cupping is known as wet cupping. In this process, the cups are applied as usual and left for several minutes. They are then removed, and a small scalpel is used to create superficial incisions in the swollen skin. This ritual bloodletting gives the treatment extra potency for the relief of low back pain
and other ailments.
Thankfully, as a medical procedure, cupping has very few risks. Dry cupping leaves red marks on the affected skin, but these are rarely painful. Occasionally, strong suction leaves deeper bruises. Again, these are seldom painful, but they tend to last for some time.
Fire cupping for low back pain can, on rare occasions lead to minor burns. When this is the case, it is likely because of an untrained practitioner being incautious with their materials. Cupping on its own is very safe.
Wet cupping carries the risk of minor pain, due to the incisions made in the skin. Also, as with any procedure that breaks the skin, there is always a small chance of infection. However, as long as the practitioner cares for their equipment correctly, this risk is minimal.
