Twitching after a rib fracture is mainly due to the painful jerking of the intercostal muscles caused by the fractured rib. As a result of the patient’s rib fracture, there is a series of painful stimuli, coupled with some degree of damage to the muscle as well. Spasms and twitching of the intercostal muscles usually occur. To alleviate this, the patient should be instructed to maintain an appropriate position and minimize activity. At the same time, bandage immobilization can be used to reduce the pain by reducing the movement of the rib fracture site. Non-steroidal anti-inflammatory analgesics can be used for pain relief. When a rib fracture occurs, there are cases of convulsions. Under the guidance of a professional doctor, you should take reasonable treatment to relieve the symptoms as soon as possible.
