If the arm is painful after a clinical examination, a cold compress can be applied to the area. Reducing local bleeding and oozing, especially of pain-causing substances, can significantly reduce pain symptoms and require reduced arm activity to prevent local injury from worsening. Oral ibuprofen extended-release capsules or diclofenac sodium extended-release capsules can be taken, these painkillers have a very good effect on reducing mild and moderate pain and also have a certain anti-inflammatory effect, which can have a certain effect on the local inflammation that may occur after the imaging. If the pain symptoms are relieved after 2 days of treatment, then you can take oral medication to relieve tendons and activate blood circulation, such as blood circulation and pain relief capsule, shujin and blood circulation capsule and so on, which can effectively relieve the local pain symptoms. If the pain is not relieved after 2 days of treatment, you should consult a doctor promptly.
