Thumb ligament strains should be treated according to the degree of injury, generally divided into mild strains, moderate strains and severe strains, and the treatment includes conservative treatment and surgical treatment. 1. Mild strain: Mild strain is usually caused by excessive activities, which can be healed without medication and can be treated conservatively. First of all, local immobilization, limiting the activities of the injured part and avoiding weight-bearing can be enough. 2. Medium and severe strains: medium and severe ligament strains require braking, in addition to localized swelling and bruising, the need to use cold compresses and bandages for localized compression to stop bleeding, which can reduce the degree of swelling and bruising. Elevation of the affected limb can also accelerate blood return, relieve swelling. Severe cases can be combined with medicines that activate blood circulation, remove blood stasis and relax tendons and collaterals, such as Yunnan Baiyao aerosol. If the pain is obvious, take anti-inflammatory painkillers such as ibuprofen orally. If the ligament is torn, surgery may be required. If the diagnosis of thumb strain is confirmed, especially with severe swelling and bruising, it is recommended to consult a doctor in time for treatment under the guidance of the doctor, and not to use medication on your own.
