My therapist has worked on my trigger points for years, along with myofascial release and massage therapy. I've had a few TP shots. THey did not help, from what I can remember. I think I was too far for TP shots when they tried them. I asked for a numbing agent before the TP shot.
Therapy helped and kept me going. My latest device is the LED and infrared light therapy. I'm a believer in them. It has put me over the edge, to better health. I'm in wellness now because of the pads. PM me if you want more info.
