Running nail cover is purple, considering that it is caused by local hypoxia, blood reflux obstruction, fungal infection and other factors.
1. Local hypoxia: if the patient runs for too long, it will reduce the oxygen content of hemoglobin in the blood of human body, which will make the organism suffer from hypoxia and cause the symptom of running with purple nail cover.
2. Obstruction of blood reflux: If the patient wears small shoes when running, the toes will be squeezed for a long time, thus affecting the blood flow of the toes, resulting in obstruction of blood reflux and causing the patient to have the symptom of purple running toenail cap.
3. Fungal infection: when running due to the feet sweat a lot, it will lead to fungal infection of the feet, which will stimulate the nail plate, leading to the destruction of the nail plate, and the symptoms of running purple nail cover. It is also accompanied by symptoms such as brittle nails that are highly prone to breakage.
If the patient’s symptoms are severe, or have not improved, he or she should go to the hospital for treatment.
