Cancer Pain

Causes of Cancer
Pain

Most cancer pain is caused by the tumor pressing on bones, nerves or other organs in your body. Pain can also be related to your cancer treatment. For example, some chemotherapy drugs can cause numbness and tingling in your hands and feet or a burning sensation at the place where they are injected. Radiotherapy can cause skin redness and irritation.


Factors That Influence
Cancer Pain

  • The type of cancer you have
  • Where it is
  • The stage of your cancer
  • Whether the cancer or treatment has damaged any nerves
  • Other factors such as fear, anxiety, depression and a lack of sleep can also affect how you feel pain.
  • If you have pain, it is very important to let your doctor know right away. If you try to put up with the pain, this can lead to nerve changes that may make the pain harder to control in the future.

Types of Cancer Pain

Cancer pain can be acute or chronic. Acute pain is due to damage caused by an injury and tends to only last a short time. For example, having an operation can cause acute pain. The pain goes away when the wound heals. In the meantime, medication can typically keep it under control.

Chronic pain is pain caused by changes to nerves. Nerve changes may occur due to cancer pressing on nerves or due to chemicals produced by a tumor. It can also be caused by nerve changes due to cancer treatment. The pain continues long after the injury or treatment is over and can range from mild to severe. It can be there all the time and is also called persistent pain. Chronic pain can be difficult to treat, but medication or other pain control methods can successfully control it in about 95 out of every 100 people.

Symptoms of Complex Regional Pain Syndrome

CRPS symptoms vary in severity and duration, although some cases are mild and eventually go away. In more severe cases, individuals may not recover and may have long-term disability.

  • Continuous burning or throbbing pain, usually in your arm, leg, hand or foot
  • Sensitivity to touch or cold
  • Swelling of the painful area
  • Changes in skin temperature — alternating between sweaty and cold
  • Changes in skin color, ranging from white and mottled to red or blue
  • Changes in skin texture, which may become tender, thin or shiny in the affected area
  • Changes in hair and nail growth
  • Joint stiffness, swelling and damage
  • Muscle spasms, tremors, weakness and loss (atrophy)
  • Decreased ability to move the affected body part
  • Medial complex or neuro origin pain from radiculopathy caused by either foraminal narrowing or neural encroachment from the herniated disc with radiculitis or a chemical radiculitis caused by a leakage of the nucleus pulposous

Causes of Complex Regional Pain Syndrome

The cause of complex regional pain syndrome isn’t completely understood. It’s thought to be caused by an injury to or an abnormality of the peripheral and central nervous systems, as CRPS typically occurs as a result of a trauma or an injury. Complex regional pain syndrome occurs in two types, with similar signs and symptoms, but different causes:

CRPS-I

Also known as reflex sympathetic dystrophy syndrome (RSD), this type occurs after an illness or injury that didn’t directly damage the nerves in your affected limb. About 90 percent of people with complex regional pain syndrome have type 1.

CRPS-II

Once referred to as causalgia, this type has similar symptoms to type 1. But type 2 complex regional pain syndrome follows a distinct nerve injury.

Cancer Pain Treatment

Content on some Pages

  • Opiate pain relievers, such as fentanyl, hydromorphone, methadone, morphine, oxycodone, and tramadol.

Oral Medications

This type of medication works to control cancer pain in most people. The key to controlling cancer pain is to take your medicine on a regular schedule. Do not wait until your pain gets bad. Pain is easier to control when you treat it just after it starts.

Be careful when taking nonprescription medicines. Talk with a pain physician before you take these medicines, especially if you have a fever or have had kidney or liver disease, gastrointestinal bleeding, or a stomach ulcer. Prescription medicines may be used alone or with other medicines. Depending on your pain, some of these medicines work better than others.

Nerve Blocks

Nerve blocks are injections containing potent anti-inflammatory agents directed at a particular nerve or nerve group that is intended to reduce inflammation and relieve pain.

Intrathecal Pump

Intrathecal pumps are also referred to as infusion pain pumps or spinal drug delivery systems. In this procedure, a pocket is made under the skin that’s large enough to hold a medicine pump. The pump is usually about one inch thick and three inches wide. A catheter is also inserted, which carries pain medicine from the pump to the intrathecal space around the spinal cord. The implants deliver medicines directly to the spinal cord, where pain signals travel. For this reason, intrathecal drug delivery can provide significant pain control with a fraction of the dose that would be required with oral medication. In addition, the system can cause fewer side effects than oral medications because less medicine is required to control pain.

Prescription Medicines and Other Treatment Options
  • Opiate pain relievers, such as fentanyl, hydromorphone, methadone, morphine, oxycodone, and tramadol.
  • Other medicines that may be used with opiate pain relievers. These medicines may be given to help your pain medicine work better or to treat your symptoms. Or they may be given for certain types of pain. These include:
    • Anticonvulsants, to help control nerve pain like burning and tingling.
    • Antidepressants, to relieve pain and help you sleep.
    • Anti-inflammatory drugs and corticosteroids (for example, prednisone or dexamethasone).
    • Bisphosphonates, such as pamidronate and zoledronic acid, to treat bone pain.
    • Local anesthetics, such as skin creams with capsaicin or lidocaine, to help relieve pain in the skin and surrounding tissues.

Radiofrequency Ablation

Radiofrequency ablation (RFA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area. RFA can be used to help patients with chronic (long-lasting) cancer pain. RFA has proven to be a safe and effective way to treat some forms of pain. It also is generally well-tolerated, with very few associated complications.



While diabetic neuropathy has no known cure, the goals of treatment are to:

  • Lumbar Sympathetic Block
  • Stellate Ganglion Block
  • Biofeedback
