How long it takes for a muscle to recover from a fall depends largely on the extent of the injury sustained. If it is a mild strain, recovery may be possible in 2-3 days after simple rest. If it is a moderate strain or muscle injury that has caused local swelling or even bruising, it may take longer to recover and may take 2-3 weeks or even a month. If the injury is very serious, or even caused a local muscle tear, recovery may take longer, a month, or even 2-3 months may be possible, and muscle injury is often accompanied by ligament damage, recovery may be more difficult, the time may be longer. The doctor will give advice and treatment according to the patient’s injury, and the treatment will speed up the recovery.
