The fact is that correcting posture first causes pain and suffering because the muscles are too weak to sustain the position. Fortunately, it is not permanent, and you may speed things up by doing certain exercises and becoming more aware of your posture. Posture problems can cause a lot of pain and discomfort in your body. If you have poor sitting posture, for example, your back will feel sore after spending some time on your computer. This is because putting excess strain on your back every day without rest will eventually lead to muscle fatigue and pain. The same thing goes for other common postural issues such as slouched shoulders, rounded spines, and bent legs. You might think that if something hurts when you stand up, then it must be your spine or joints. However, this is not always the case. For example, let's say you have flat feet and get pain when standing up straight because of stress on the arches. Although this pain isn't found anywhere near your spine, it still belongs to the foot problem category because it results from excessive pressure being placed on the feet. Similarly, if you feel pain in your lower back when trying to correct your posture, it means your muscles are used up already and need time to recuperate. So rather than worrying about what category your particular posture problem falls into, focus on strengthening the muscles that contribute to these difficulties first.
