According to a report by Yahoo, Kaoru Mitoma has suffered a hamstring injury, and if it is a moderate injury, it will take about 4 weeks to recover.
The report stated that Kaoru Mitoma started in the home game against Wolves and was substituted off the field due to injury in the second half of the game, experiencing pain in the back of his left thigh. His injury is a hamstring (back of the thigh) injury.
Japan national team coach Hajime Moriyasu also spoke about the matter, saying, "I have not yet received an accurate report on this matter," and then added, "I sincerely hope it is just a minor injury, but the information I have received so far gives the impression that it is probably not a minor injury."
A hamstring muscle strain refers to the separation of muscle and fascia. According to the degree of injury, it can be divided into three levels: mild, moderate, and severe. The degree of damage ranges from mild tissue damage to complete muscle rupture, and the recovery period varies greatly, from a few weeks to several months.
A muscle strain can be diagnosed by MRI if hematoma or bleeding symptoms are found. If the fascia surrounding the muscle shows a white area in the image, it means that there is internal bleeding. Fascia tears also fall into the category of muscle strains, meaning a higher degree of damage.
If it is a mild injury, you only need to stop exercising and rest for 1 to 2 weeks, and the blood stasis in the body will be absorbed and healed by itself; however, moderate and above injuries usually take several weeks to return to competitive form. Once a fascia tear occurs, the repair cycle takes about 4 weeks, during which time it is impossible to participate in sports training.
A severe injury is a serious condition in which the muscle or tendon is completely ruptured, and complete recovery takes more than 2 to 3 months, and in some cases, surgery is required. The injured person will experience severe pain and may even have difficulty walking independently, but Kaoru Mitoma walked off the field on his own at the time.
