Spontaneous Bruising

Namaste! Im not sure how familiar anyone here is with Khundalini Lounge on Youtube. I finished her 40 day challenge and am on day 5 of her chakra balancing series. After day 4, heart balancing, i noticed spontaneous bruising along the front of my chest along my rib connections and a large darker on on the right pectoral muscle, the top of my right shoulder by over the joint and then my right forearm. I think the shoulder bruise may have been from day 3. I noticed that my thoracic spine also popped and adjusted as i sat there. With every breath, especiall deep, i could feel something in my back adjust/clock. I believe to be ribs head. Anyway. Can anyone tell me if this is fascial, energetic like along maridian points, or if its muscular.
