The Pain
It's safe to say most of us are not big fans of pain. Nevertheless, it is one of the body's most important communication tools. Imagine, for instance, what would happen if you felt nothing when you put your hand on a hot stove. Pain is one way the body tells you something's wrong and needs attention.
But pain -- whether it comes from a bee sting, a broken bone, or a long-term illness -- is also an unpleasant sensory and emotional experience. It has multiple causes, and people respond to it in multiple and individual ways. The pain that you push your way through might be incapacitating to someone else.
Even though the experience of pain varies from one person to the next, it is possible to categorize the different types of pain. Here's an overview of the different types of pain and what distinguishes them from one another.
Acute Pain and Chronic Pain
There are several ways to categorize pain. One is to separate it into acute pain and chronic pain. Acute pain typically comes on suddenly and has a limited duration. It's frequently caused by damage to tissue such as bone, muscle, or organs, and the onset is often accompanied by anxiety or emotional distress.
Chronic pain lasts longer than acute pain and is generally somewhat resistant to medical treatment. It's usually associated with a long-term illness, such as osteoarthritis. In some cases, such as with fibromyalgia, it's one of the defining characteristic of the disease. Chronic pain can be the result of damaged tissue, but very often is attributable to nerve damage.
Both acute and chronic pain can be debilitating, and both can affect and be affected by a person's state of mind. But the nature of chronic pain -- the fact that it's ongoing and in some cases seems almost constant -- makes the person who has it more susceptible to psychological consequences such as depression and anxiety. At the same time, psychological distress can amplify the pain.
About 70% of people with chronic pain treated with pain medication experience episodes of what's called breakthrough pain. Breakthrough pain refers to flares of pain that occur even when pain medication is being used regularly. Sometimes it can be spontaneous or set off by a seemingly insignificant event such as rolling over in bed. And sometimes it may be the result of pain medication wearing off before it's time for the next dose.
Other Ways Pain Is Classified
Pain is most often classified by the kind of damage that causes it. The two main categories are pain caused by tissue damage, also called nociceptive pain, and pain caused by nerve damage, also called neuropathic pain. A third category is psychogenic pain, which is pain that is affected by psychological factors. Psychogenic pain most often has a physical origin either in tissue damage or nerve damage, but the pain caused by that damage is increased or prolonged by such factors as fear, depression, stress, or anxiety. In some cases, pain originates from a psychological condition.
Pain is also classified by the type of tissue that's involved or by the part of the body that's affected. For example, pain may be referred to as muscular pain or joint pain. Or a doctor may ask you about chest pain or back pain.
Certain types of pain are referred to as syndromes. For instance, myofascial pain syndrome refers to pain that is set off by trigger points located in the body's muscles. Fibromyalgia is an example.
Pain Caused by Tissue Damage
Most pain comes from tissue damage. The pain stems from an injury to the body's tissues. The injury can be to bone, soft tissue, or organs. The injury to body tissue can come from a disease such as cancer. Or it can come from physical injury such as a cut or a broken bone.
The pain you experience may be an ache, a sharp stabbing, or a throbbing. It could come and go, or it could be constant. You may feel the pain worsen when you move or laugh. Sometimes, breathing deeply can intensify it.
Pain from tissue damage can be acute. For example, sports injuries like a sprained ankle or turf toe are often the result of damage to soft tissue. Or it can be chronic, such as arthritis or chronic headaches. And certain medical treatments, such as radiation for cancer, can also cause tissue damage that result in pain.
Pain Caused by Nerve Damage
Nerves function like electric cables transmitting signals, including pain signals, to and from the brain. Damage to nerves can interfere with the way those signals are transmitted and cause pain signals that are abnormal. For instance, you may feel a burning sensation even though no heat is being applied to the area that burns.
Nerves can be damaged by diseases such as diabetes, or they can be damaged by trauma. Certain chemotherapy drugs may cause nerve damage. Nerves can also be damaged as a result of stroke or an HIV infection, among other causes. The pain that comes from nerve damage could be the result of damage to the central nervous system (CNS), which includes the brain and spinal cord. Or it could result from damage to peripheral nerves, those nerves in the rest of the body that send signals to the CNS.
The pain caused by nerve damage, neuropathic pain, is often described as burning or prickling. Some people describe it as an electrical shock. Others describe it as pins and needles or as a stabbing sensation. Some people with nerve damage are often hypersensitive to temperature and to touch. Just a light touch, such as the touch of a bed sheet, can set off the pain.
Much neuropathic pain is chronic. Examples of pain caused by damaged nerves include:
Central pain syndrome. This syndrome is marked by chronic pain that stems from damage to the central nervous system. The damage can be caused by stroke, MS, tumors, and several other conditions. The pain, which is typically constant and may be severe, can affect a large part of the body or be confined to smaller areas such as the hands or feet. The pain often can be made worse by movement, touch, emotions, and temperature changes.
Complex regional pain syndrome. This is a chronic pain syndrome that can follow a serious injury. It's described as persistent burning. Certain abnormalities such as abnormal sweating, changes in skin color, or swelling may be noticed in the area of the pain.
Diabetic peripheral neuropathic pain. This pain comes from nerve damage in the feet, legs, hands, or arms caused by diabetes. Individuals with diabetic neuropathy experience various kinds of pain including burning, stabbing, and tingling.
Shingles and postherpetic neuralgia. Shingles is a localized infection caused by the same virus that causes chickenpox. The rash and associated pain, which can be debilitating, occurs on one side of the body along the path of a nerve. Postherpetic neuralgia is a common complication in which the pain from shingles lasts more than a month.
Trigeminal neuralgia. This condition causes pain as a result of inflammation of a facial nerve. The pain is described as intense and lightning like, and it can occur in the lips, scalp, forehead, eye, nose, gums, cheek, and chin on one side of the face. The pain can be set off by touching a trigger area or by slight motion.
Our Solution
Today, spas offer everyday people a wide variety of services, many of which can be very beneficial to the health of your spine.
Massage
The key to a healthy body is good circulation and massage is a great way to increase the flow of blood throughout the body. Massage has become a popular way to relieve muscle tension and spasm, inflammation, fluid retention, aches, stiffness, and pain. Other benefits include improved circulation, flexibility and greater range of motion, and tissue elasticity. Massage therapists use their hands or special tools to knead, rub, and stroke muscles. Sometimes lotion or oil is applied to the skin to reduce friction. If you have mild back pain or occasional stiffness, a massage may be just what you need.
The use of massage for the treatment of low back pain is popular and has a long history of use across a range of cultures. Massage is manipulation of soft tissue (i.e. muscles and fascia) using the hands or a mechanical device, to promote circulation and relaxation of muscle spasm or tension. (1) There are many styles of massage and massage may be provided as a stand-alone treatment or as part of a comprehensive treatment plan. (2) Despite a lack of methodologically sound trials, it has been accepted that this non-invasive therapy offers several potential benefits:
• Massage therapy affords patients relief without overriding their desire to limit their of use drugs
• Massage therapy is non-addictive compared to pharmaceuticals taken for pain
• Massage therapy is low in cost compared to many prescription drugs
• Massage therapy rarely has adverse effects (3)
A trial testing the effectiveness of massage for chronic low back pain (LBP) showed that massage significantly reduced pain and improved functioning compared to sham laser post-treatment and after one month. Massage combined with exercise and education was significantly better than sham laser on both pain and function.
Acupuncture
Acupuncture is the 5000-year-old Chinese art of healing that involves the insertion of very fine, sterile needles into specific parts of the body called Meridian points. This therapy stimulates and activates the body's immune and healing systems. Acupuncture is used to treat many disorders, including chronic pain, headaches, back, neck, or muscle pain, stress, and arthritis. Be sure to find an acupuncturist who is certified and experienced.
A recent study published in 2005, reviewed 33 articles of acupuncture trials, and concluded that acupuncture is more effective than sham acupuncture and no additional treatment was required for providing short-term relief of chronic low back pain. This short-term relief seems to be sustained long-term; however, a sustained effect has not been established, as long-term follow up data is not yet available. More research is needed to evaluate acupuncture's effect on acute low back pain, and the evidence comparing acupuncture to other active treatments is inconclusive. At this time current estimates of acupuncture's effects on chronic low back pain are preliminary as several large studies are currently ongoing. However, anecdotal evidence supports acupuncture to be a viable adjunct to traditional medicine.
