How to treat a swollen hand pinched by a door depends on the severity of the condition, and its treatment usually includes physical therapy, medication, surgery, and so on.
1. Minor crush injuries: within 72 hours of the hand being swollen by the door, cold compresses can be applied to the swollen area, and then hot compresses can be applied after 72 hours, which can promote the subsidence of swelling and generally provide relief. If the swelling and pain is obvious, it can also be appropriate with some non-steroidal anti-inflammatory drugs, such as diclofenac sodium, ibuprofen and so on.
2. When the hand is accompanied by skin breaks, but no damage to the bones and muscles, first of all, local disinfection can be carried out on the skin breaks, and if the wounds are large, the wounds should be bandaged after disinfection in order to avoid infection.
3. If there is nerve damage or fracture, external fixation or surgery should be chosen according to the specific situation.
The above medications should be used under the guidance of a doctor. When your hand is swollen after being pinched by a door, if the symptoms are not relieved or the pain worsens after simple treatment such as applying ice packs, it is recommended that you seek medical attention to clarify the extent of the injury and receive appropriate treatment.
