In most cases, it is part of the body's adaptation process and develops favourably when there is proper guidance.<\/p>\n<hr data-start=\"1446\" data-end=\"1449\" \/>\n<h2 data-start=\"1451\" data-end=\"1481\">What is chronic low back pain?<\/h2>\n<p data-start=\"1483\" data-end=\"1716\">We talk about <strong data-start=\"1494\" data-end=\"1516\">chronic low back pain<\/strong> when the pain persists for more than three months. Here, the scenario changes. Pain is no longer just a local response to a physical stimulus, but involves the nervous system more significantly.<\/p>\n<p data-start=\"1718\" data-end=\"1733\">In chronic pain:<\/p>\n<ul data-start=\"1734\" data-end=\"1992\">\n<li data-start=\"1734\" data-end=\"1802\">\n<p data-start=\"1736\" data-end=\"1802\">the intensity of the pain doesn't always correspond to the condition of the tissues,<\/p>\n<\/li>\n<li data-start=\"1803\" data-end=\"1845\">\n<p data-start=\"1805\" data-end=\"1845\">tests may not justify the symptoms,<\/p>\n<\/li>\n<li data-start=\"1846\" data-end=\"1905\">\n<p data-start=\"1848\" data-end=\"1905\">fear of movement and insecurity become frequent,<\/p>\n<\/li>\n<li data-start=\"1906\" data-end=\"1992\">\n<p data-start=\"1908\" data-end=\"1992\">factors such as stress, sleep, previous experiences and expectations have a greater weight.<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1994\" data-end=\"2157\">This doesn't mean that \u201cthe pain is in the head\u201d. <a href=\"https:\/\/osteosalvador.pt\/en\/relieving-chronic-pain-is-the-truth\/\">It means that the body and nervous system are more sensitive<\/a>, The pain is maintained by multiple factors.<\/p>\n<hr data-start=\"2159\" data-end=\"2162\" \/>\n<h2 data-start=\"2164\" data-end=\"2195\">The difference isn't just time<\/h2>\n<p data-start=\"2197\" data-end=\"2371\">A common mistake is to think that the only difference between acute and chronic pain is the number of weeks or months.
