If you spend a long time in the toilet, you can take the following measures: 1. It is recommended to stay in bed and keep your lower limbs warm. Ankle function exercise should be carried out when lying flat, requiring patients to keep their lower limbs straight and practice ankle dorsiflexion and plantarflexion. Through the reciprocating motion of ankle joint, it can stimulate the contraction of lower limb muscles, and then accelerate the blood circulation of lower limb. After the blood circulation of lower limbs is restored, the numbness symptoms will be obviously relieved. 2. If the patient often has this symptom, it is suggested that the patient should not sit in the squatting toilet, but can sit in the toilet instead. If you change to squat, you will still have this symptom. It is recommended that patients do more aerobic exercise and jog on a flat road. 3. If the symptoms still recur after the above treatment, it is recommended that the patient go to the orthopedics department of a hospital above the second level as soon as possible to find out whether there is peripheral nerve or vascular disease.
