If there is no local allergy or rash during the recovery period after dislocation, it is generally considered to be a normal condition, but it may also be an abnormal condition such as nerve damage or poor local blood circulation. After dislocation, the dislocated joint needs to be reset, and the surrounding soft tissues may be congested and edematous. During the recovery period, the hematoma of the surrounding soft tissues will be slowly absorbed, and the damaged microvessels will be slowly repaired, and there may be a slight itching sensation during this process. If local skin rash occurs due to allergy or other reasons, itching may also occur, at this time you can use local anti-inflammatory and anti-itching ointment under the guidance of the pharmacist for treatment. Itching may also occur when the nerves are damaged or the local blood circulation is poor. When itching occurs during the recovery period after dislocation and local skin allergies or rashes are ruled out, if the itchiness persists or worsens, or even if other symptoms appear, you should consult a doctor immediately to clarify the cause of the disease and receive appropriate treatment.
