I broke my back last year and am still having problems with my scapula area- the lower muscle. My PT started doing this on my back. It has changed my pain and the way that I carry myself. It lifts the soft tissue underneath where the cup is placed to increase circulation, which in turn helps reduce swelling.

Why do you need to open your lymph nodes in advance?

Are you under a doctor's care for this?

From Cedars Siani-
Can I Do Lymphatic Drainage Massage Techniques on Myself?
Yes, and the technique is simple. The idea is to use very light pressure to massage the area and push fluid that’s causing swelling back toward the heart. Move your fingers in a motion that creates the letter “C,” gently massaging tissues that are NOT swollen.

Since lymphatic drainage massage acts on the skin, it’s important to avoid using oils or lotions during the massage.

There are other ways to pamper your lymphatic system, too, including:

Deep breathing. Breathing slowly and deeply can help move fluid through the lymph vessels and nodes. Place both hands on your belly and focus on expanding your belly as you inhale and contracting your belly as you exhale.
Physical activity. Exercise helps move fluid throughout the body. Even a 15- to 20-minute stroll can help your body shift fluid around and eliminate waste. A short jog while focusing on deep breaths also does the trick.
Dry brushing. Dry brushing has gained popularity in recent years for its ability to keep the lymphatic system healthy while exfoliating the skin. Just move the brush in circular motions starting at the extremities and working your way toward the trunk of the body.
Swimming. Moving through water provides built-in compression for your body, so swimming is a great way to get your lymph fluid moving.
Tap your skin. Tapping the area just above the collarbones with light pressure can activate the lymph capillaries beneath the skin.

I follow a detox dr and her videos tell you which areas to basically stimulate by tapping or rubbing. Basically to “wake up” your lymphatic drainage system if it is congested.
