For sure get a vet out ASAP. It does look like a tendon injury. Cold therapy, bandaging, stall rest and hand-walking are the basics that you can do until your vet cand make a proper diagnosis and give you a treatment routine.
Is that a wound on the leg where the bow seems the worst? It might be just severe swelling on the area of the wound, but I doubt it.
There are lots of treatment options for bows, like shock wave, magnetic therapy, aqua therapy, ultrasound, and injections often used in conjunction with NSAID's. Diagnosis can occasionaly be sorta pricey, but IMO, it's worth it to get the most accurate diagnosis. Palpation can be great, but there are some great diagnostic technologies out there, too.
If you are not handy with a bandage and different liniments and their functions, maybe seek out a friend or trainer more experienced to give you a hand. Good luck - keep us posted about what the vet says!
