Ligament injuries are generally divided into two cases, one is produced obvious skin injury, can be treated with antibiotics, and the other is closed ligament injury, there is no wound on the skin, can be treated with non-steroidal anti-inflammatory drugs. If the ligament injury is caused by some violent behavior, usually there will be severe trauma, which may produce bacterial infection, you can use antibiotics such as cefaclor dispersible tablets, amoxicillin capsules, penicillin V potassium tablets, etc., to prevent infection. If it is a closed ligament injury, the local skin or mucous membrane is intact, and there is no wound to communicate with the outside world, this situation usually produces aseptic inflammation, you can use ibuprofen extended-release capsules, meloxicam dispersible tablets, naproxen tablets and other non-steroidal anti-inflammatory drugs, to alleviate the pain, swelling and other symptoms. Drugs are only one way to treat ligament injuries, if the condition is more serious, surgical treatment may also be required. Patients are advised to consult the doctor in time, choose the appropriate treatment and take the medication as prescribed by the doctor to avoid adverse consequences.
