Pain can be difficult to define and identify, with various sensations and degrees of severity. Unexplained pain can be caused by nerve dysfunction, autoimmune disorders, nutritional deficiencies, inflammation, and psychological factors. The brain is responsible for all pain, including that which is unexplained.
Pain is one of the hardest words to define. It can come with many sensations – aching, burning, tearing, stabbing – and in varying degrees of severity, but one characteristic that everyone can agree on is that the pain is annoying. In many cases, one can at least make an informed guess about the source of a pain. The location of some types such as joint pain, however, can make identification difficult. Additionally, many conditions cause a generalized type of pain that may seem unidentifiable at first glance. Disorders that can cause unexplained pain include nerve dysfunction, an autoimmune disorder, nutritional deficiencies, and somatoform pain or other psychological sources.
Inflammatory diseases, particularly around the bones and joints, can cause swelling and irritation. Because these disturbances occur within the body, the pain may initially seem inexplicable. Such inflammation is often the result of a minor injury or infection. The associated pains can spread along the bones, making it difficult to pinpoint the source of the pain, thus leading to seemingly inexplicable pain.
Certain ailments such as autoimmune diseases and cancer can also wreak havoc on delicate internal structures. In the former case, conditions such as lupus make it difficult for the body’s defensive white blood cells to distinguish between harmful substances and normal body tissue. As a result, the immune system actually attacks the body, which will likely lead to pain. Cancer cells have a similar damaging effect on healthy tissue, particularly as the disease spreads and invades various areas of the body. Everything from glands to blood vessels can be targeted in these serious conditions and in turn create a variety of complications for the body, including unexplained pain.
Another major source of pain in the absence of an apparent cause is malfunctioning nerves. Nerve endings can misfire and cause subsequent tingling or burning sensations. These periodic discomforts can occur anywhere in the body and can be worse at night or when touched. Underlying conditions such as diabetes, celiac disease and autoimmune diseases can lead to nerve damage. For some cases, the exact causes of these conditions are unknown.
Depriving the body of essential nutrients can also weaken various areas, leading to seemingly inexplicable pain. Vitamin D deficiency, for example, can make bones brittle and more susceptible to the wear and tear associated with them. Other deficiencies can take a toll on your muscles and skin.
One of the body’s most mysterious and most active organs, the brain, is ultimately responsible for all pain, whether it is explained or unexplained. This organ sends and receives signals that the body recognizes as pain. Sometimes, the brain can send these signals by accident, though the exact reason for this response is largely a mystery. Fibromyalgia is a condition believed to be caused in part by sensitive pain receptors in the brain and is characterized by extreme tiredness and pain as a result of applied pressure. Additionally, certain psychological factors such as stress and depression can alter brain chemistry and contribute to aches and general malaise.
