Joint and ligament sprains are relatively easy to recover. Many people slowly develop chronic inflammation due to long-term non-inflammation, resulting in a certain degree of tissue degeneration, which will bring certain difficulties to treatment. Generally, hyperthermia must be started 1-2 days after sprain. The reason is to absorb congestion and reduce the stimulation of congestion to soft tissue. Generally, after the congestion is completely absorbed, the edema and inflammation of the tissue are completely eliminated. We have come into contact with many patients with sprains, some of whom have not recovered for 1-2 months, and their symptoms are quite serious. Once the microwave therapeutic instrument is used for hyperthermia for 30 minutes each time, the pain symptoms can be obviously alleviated after treatment, which is the effect of local anti-inflammatory and detumescence. The problem of 1 week for some patients 1-2 months can be completely eliminated. It can last for 2-3 weeks if conditions permit. In a word, proper method is the most critical problem in the treatment of this kind of disease, but it is not so complicated. Unless fracture or rupture is involved, surgical cooperation is required. It is also very simple for patients to make a diagnosis by filming.
