Dumbbell elbow pain may be muscle or tendon injuries at the elbow joint, or it may be a joint slip fracture. 1. Muscle injury: If the patient does not warm up before practicing dumbbells, or the training intensity is beyond the range of their own ability to withstand, will cause elbow joint injury, muscle strain, soft tissue such as tendon ligaments and other injuries, aseptic inflammation, which leads to elbow joint pain. 2. Joint dislocation: If the patient’s training posture is not appropriate, so that the joint bearing part is not appropriate, it is easy to lead to a slight dislocation of the elbow joint, or even traumatic elbow fracture, which will lead to pain. If the patient’s elbow pain can’t be relieved and is unbearable, he should go to the hospital in time for examination and receive treatment after clarifying the cause of the disease.
