Here is what I noticed: The cough I had subsided. The irritating mucous in my throat and chest and cleared. My voice was clear. My body began to feel colder because I was lighter and freer from restraints and blocks. When I placed it near my left scapula, on my back, I felt small rumbling vibration. Great, it opened up energy.
So, yes, I recommend that everyone self treat, especially to complement and help continue the body's fascia working from the Myofascial Release session.
