Lumbago occurs more frequently when digging, transplanting or building a house in the garden. Even with a lengthy renovation of the home, acute back pain often occurs. Those affected, who otherwise work a lot in the office, can quickly overload their trunk muscles due to the often physically heavy work in unfavorable positions (for example, working overhead for days because a ceiling has to be renovated).
As already written, trauma or unhealed muscles or joints after surgery can also lead to imbalances in the musculoskeletal system and thus to lumbago.
Other factors that promote lumbago are: Little exercise, one-sided competitive sports, poor diet, stress, worries and problems, weak back and/or abdominal muscles or an incorrect ratio of muscles to each other, wrong lying (wrong mattress) or wrong sitting (wallet in your pocket and constantly sitting crookedly), wrong shoe insoles. As you can see, there are many influencing factors.
