Ankle sprain is a minor disease, but many doctors ignore it because of the minor disease, resulting in the patient’s pain for a long time. Recently, Dr. Luo treated many cases of ankle sprains that could not be cured, so he had the feeling to make a topic with ankle sprains again. Most of the joint sprains are not visible on the film, but some of them have a slight misalignment. The textbook classifies this as a ligament laceration, and the treatment described in the textbook is all local treatment. In the clinic, many patients with sprains are found to be injured not only locally, but also in their upper soft tissues due to the transmission of force received strain injury, such as the treatment of local, some patients have a long treatment period, several months or even years have accompanying symptoms, some of the sprains do not heal for a long time resulting in unbalanced force on both lower limbs and then evolved into spinal problems and pain in the waist and legs, such cases are clinically The culprit is not the patient but the limited level of knowledge of our doctors. Clinical ankle sprains are generally divided into two categories, valgus and valgus positions. A sprain is like a tug of war, where the tissues underneath are stretched and the tissues above are stretched in the opposite direction. When a sprain occurs in the valgus position, the tibialis anterior muscles in the ankle joint will also be pulled in the opposite direction, resulting in strain on the upper part of the attached bone. Treating the ankle joint along with the upper pressure points can often have an immediate effect and significantly shorten the treatment period. In many cases, we only treat the upper pressure point and the pain in the ankle joint is immediately relieved. When the ankle joint is sprained in the inversion position, the calf flounder muscle group will also be pulled in the opposite direction, resulting in the upper part of the bone being strained, and we can often touch the obvious knot in the upper 1/3 of the tibia (the knot is often deeper here and can only be touched by deep pressure in the direction of the tibia), so treating the inner ankle with the release of the upper knot will improve the effect significantly (note: some knots even form near the thigh point). (Note: some knots are even formed near the thigh point of the thigh)! I won’t discuss the issue of ankle misalignment, as I have written about it before. For old sprains of the ankle joint, to a large extent doctors misdiagnose the problem because they ignore the upper part of the problem, and in the clinical treatment of old sprains we mainly take the upper tendon knot point to loosen.
