1. First of all, you need to know about your old injury. How did you hurt your arm? Do you have any old injuries such as fracture, fracture or muscle strain, or hit the elbow tendon? Injuries that hurt muscles and bones generally need long-term rehabilitation, do a good job of rehabilitation massage, and you can also compare the healthy analogy exercises on the other side.

I don't think it's necessary to worry about the heart problem mentioned on the first floor. Although the little finger takes the Yin Meridian from the inside of the hand, what you said through the account is generally not the muscle spasm caused by the heart, but the muscle injury caused by excessive overload exercise without warm-up and preparation.

3, but the first floor can learn from the question-and-answer method, that is, massage therapy with Chinese medicinal liquor to relax muscles and help them recover. At the same time, we should also do more repair exercises and exercise consciously.

Two. Lessons learned

1, the most important thing in exercise is not to cause sports injuries, and the second is to achieve the purpose of fitness exercise. So in the future, you should know your upper limit of ability and do appropriate exercise.

2. While exercising, strengthening nursing and medical anatomy knowledge can greatly improve self-protection awareness and self-recovery ability, and greatly reduce the possibility of injury. If you suffer from loss, you will gain wisdom, or if you become a good doctor after a long illness, you will always gain something. Don't worry too much. Keep a good attitude, believe in your body's recovery ability, understand it through various channels, and then carry out targeted understanding and treatment.

Just an empirical answer, unprofessional. If you have any questions, please ask. I wish you a speedy recovery!
