Recurrence of pain from old injuries is more common in the clinic, and the pain recurrence is usually more obvious when the climate alternates between cold and warm. Treatment can be divided into two categories: local treatment and systemic treatment. Locally, you can use Fitalin ointment and safflower oil to apply externally, pay attention to local warmth, and if you have the conditions, you can go to the rehabilitation department of the hospital to do local infrared irradiation and local massage, which can promote blood circulation. Patients can take some Chinese medicines that can activate blood circulation and relieve pain, such as Shujiweiqi Tablet, and vitamins that can regulate the nerves, such as Gouweixin and Vitamin B6.
