I was bucked off a horse (not mine :) and my foot got stuck in the stirrup. I was dragged, stomped on, and kicked. I had multiple deep tissue and muscle bruises and a sprained ankle. My Photizo Vetcare arrived the next day (coincidence) and has helped SO much with pain, swelling, and bruising. I have also used it on my horse. He is a bit locked up near his wither and has a bit of a hunter's bump. I used it on both areas and he licked and chewed and seemed to love it. Also using it on my bad knee and my dog who was limping...all within the last couple weeks :). Works so well! The pictures show my one very dark bruise. I held the Photizo in two separate spots and did 4 cycles for each spot and you can see where the bruise lightened to pink! Also, one pic of another bruise. I treated most of it but left one spot at the end and it is easy to see what was treated.
