how long does it take for muscle repair
Thera not a simple answer. It has to do with the severity of the injury(some need surgical repair) and the location. Usually, it's not a good idea to put an injured muscle to complete rest. Continue to use it mildly and pain is your indicator. Some muscles with good blood supply will heal quickly, within a few days. Others, that need medical attention or are used constantly (muscles between ribs that are used with every breath) may take weeks. Another factor is age. After 30, it just takes longer to heal.
