Injuring your fingers is a common occurrence in BJJ. In this video I discuss an injury I sustained to one of my fingers and show you how I assessed the finger to evaluate the injury.
This obviously effected gripping and gi training as well as no-gi grappling. I have found that taping the fingers when injured has been a really effective way to protect the hand/fingers as well and I will share a specific taping technique for this injury in a follow up video.
Remember that seeing a medical professional such as a Doctor or a Physical Therapist is always a good idea for evaluating and treating any injury.
