At 19 years of age, recurrent lower back strain is usually related to muscle spasm, ligament strain, or posture-related stress, even if recovery is taking longer this time. A cracking sound while bending is commonly due to joint cavitation or tight soft tissues and is usually harmless if not associated with sharp pain or leg symptoms. The delayed recovery can happen if the muscles have not fully rested or are being repeatedly strained. Continue avoiding forward bending, heavy lifting, and prolonged sitting for now.
