The symptoms of nodular fasciitis are typical, mainly manifesting as subcutaneous, subfascial and intramuscular nodular changes, and tend to expand rapidly within a short period of time, resulting in diffuse local changes and possibly localized pain, and its complications are mainly dry syndrome. It is usually manifested as subcutaneous nodular changes, which can be detected by palpation and can occur in any part of the body without a fixed location. 2. Fascial type: The nodular changes are mainly manifested as superficial fascial and subcutaneous fat interval expansion, the boundary is not very clear and shows infiltrative growth. 3. Intramuscular type: the lesion develops deeper into the muscle and erodes into the skeletal muscle, which is a more serious manifestation of nodular fasciitis and requires the help of imaging and ultrasound to clarify the condition and treatment must be combined with surgery. Other symptoms of localized pain and numbness: This is a symptom that can easily appear after the development of nodular fasciitis in the intramuscular stage. The lesion is attached to the skeletal muscle, so once it is touched during activity or if it grows to affect the normal activities of the skeleton, the symptoms of pain and numbness will appear, requiring timely examination and surgical intervention.
