Myofascial cupping, also known as myofascial decompression therapy, is a safe, non-invasive treatment used to reduce pain and inflammation as well as improve blood flow and lymphatic drainage. It can also be used to improve muscle tension and adhesions from scars, allowing improved mobility. During cupping, a silicon, plastic, or glass cup is placed over the symptomatic area. A rubber pump is then used to create a vacuum seal and cause the skin to rise. By placing tension on the connective tissue and muscles underneath the skin, this helps restart the healing process, improving circulation and reducing muscle fatigue.
The two types that are used in our clinic are dry cupping and oil/sliding cupping. Dry cupping is the above described process in which the cups are left in one position without movement once sealed. The cups are then left for no more than ten minutes. Oil/sliding cupping uses an emollient, such as massage oils, to reduce friction and allow the cups to be moved across the skin during treatment.
Side effects that may be caused by cupping include lightheadedness, dizziness, sweating, nausea, or bruising. If bruising occurs, the circular marks should disappear within one to ten days after treatment. If side effects occur, they should be apparent during or immediately after the end of the treatment.
