The pain threshold varies from person to person and is influenced by a variety of factors, such as age, gender, personality, psychological state, and the nature of the pain-causing stimulus. Clinically, some pain is caused by injurious stimuli, while others have unclear stimulus factors. Various stimuli that can cause pain do not cause pain when the stimulus intensity is very weak; pain is felt only when the stimulus reaches a certain intensity. The so-called “pain threshold” refers to the minimum amount of stimulus that causes pain. Clinically, some pain is caused by injurious stimuli, and some pain is stimulated by unclear factors. A lower pain threshold increases sensitivity to pain, and normal stimuli, such as changes in the physiological range of the body, can also cause pain. Over time, this can lead to changes in mood and dysfunction in the body, leading to vascular disease, etc. Persistent muscle contraction leads to vasogenic headache and myotonic headache, causing pain to the patient. The elevated pain threshold also fails to feel pain or delayed response to stimuli beyond the pain threshold, and the disease cannot be detected and diagnosed early, and the opportunity for early treatment is lost. In short, the elevation or lowering of the pain threshold is not good for the human body. Bedridden: Bedridden (or long-term bedridden, bedridden) refers to a clinical phenomenon in which the elderly are partially or completely in need of care and attention due to long-term illness and disability, including long-term bedridden, chair-bound and indoor living. The consequences of prolonged bed rest are serious, easy to complicate pulmonary infections, bedsores, malnutrition, lower limb venous thrombosis, etc. Once it happens, there is less hope of recovery and getting up again, so prevention should be emphasized. Traction headache: Sudden onset of severe headache after sitting, often accompanied by nausea, vomiting, because of the further decline in intracranial pressure, intracranial pain-sensitive tissues lost the cerebrospinal fluid support and pulled, so it belongs to traction headache. Headache is a common clinical symptom, and pain confined to the upper part of the skull, including the brow arch, the upper edge of the ear chakra and the area above the line of the external occipital ridge, is usually referred to as headache. Headache and dizziness: A common problem in the elderly. The main manifestation is dizziness accompanied by mild headache. The causes of headache are complex, including intracranial and extracranial. There are localized headaches and systemic ones. There are also many headaches for which no cause can be found to date.
