What Is Pain
Pain is an uncomfortable feeling that tells you something may be wrong. It can be steady, throbbing, stabbing, aching, pinching, or described in many other ways. Sometimes, it’s just a nuisance, like a mild headache. Other times it can be debilitating.
Pain can bring about other physical symptoms, like nausea, dizziness, weakness or drowsiness. It can cause emotional effects like anger, depression, mood swings or irritability. Perhaps most significantly, it can change your lifestyle and impact your job, relationships and independence.
Pain is classified as either acute or chronic. Acute pain is usually severe and short-lived, and is often a signal that your body has been injured. Chronic pain can range from mild to severe, is present for long periods of time, and is often the result of a disease that may require ongoing treatment.
Because perception and tolerance of pain vary widely from individual to individual, pain is difficult to define and describe. Essentially, pain is the way your brain interprets information about a particular sensation that your body is experiencing. Information (or “signals”) about this painful sensation are sent via nerve pathways to your brain. The way in which your brain interprets these signals as “pain” can be affected by many outside factors, some of which can be controlled by special techniques.
Acute pain is of short duration, usually the result of an injury, surgery or illness. This type of pain includes acute injuries, post-operative pain and post-trauma pain.
Chronic pain is an ongoing condition, such as back and neck pain, headaches, complex regional pain syndrome Type 1 (reflex sympathetic dystrophy), neuropathic pain (nerve injury pain), musculoskeletal pain, and pain related to illness. Your physician may refer you to the Pain Management Center because your chronic pain condition has not responded to conventional therapies.
Types OF Pain


All pain is an individual human experience that is entirely subjective and can only be truly appreciated by the person experiencing the pain.
Acute pain is pain that lasts for a short time and occurs following surgery or trauma or other condition. It acts as a warning to the body to seek help. Effective timely treatment is essential to prevent transition to chronic pain.
Chronic pain is pain that lasts beyond the time expected for healing healing following surgery or trauma or other condition. It can also exist without a clear reason at all.
Some forms of chronic pain, for example pain associated with severe osteoarthritis, may be treated with therapy which may include medication or surgery; however other types of chronic pain, such as neuropathic pain or migraine, may be far more difficult to diagnose and treat.
A large body of basic research indicates that chronic pain is associated with neuroplastic changes in the nervous system at peripheral, spinal cord and brain levels. Thus chronic pain is shown to have a distinct pathology that often worsens over time, and constitutes a serious separate disease entity.
Left untreated, chronic pain can have a devastating impact on all aspects of sufferers’ lives. About 65 percent of people with chronic pain report interference with daily activities including sleep, sex, work, exercise and routine self-care, which can have a negative effect on personal relationships, social interactions and lifestyle.
Cancer pain is one of the most feared aspects of cancer. It can occur in patients with both early stage and advanced disease, and in cancer survivors as a severe and debilitating side-effect of treatment.
Causes Of Pain
What Causes Chronic Pain?
Anything from a bad mattress to stomach ulcers can cause chronic pain. While it may begin with an injury or illness, pain can develop a psychological dimension once the physical problem heals.
Nerve Pain
When nerve fibers get damaged, the result can be chronic pain. Read about the very common causes of neuropathic pain, like diabetes.
What Causes Chest Pain?
Certainly chest pain is not something to ignore. But you should know that it has many possible causes.
