Chronic Pain


What is pain?
Pain is the body’s natural response to harm. Pain occurs when special pain receptors at the end of the nerves, called nociceptors, are turned on because of an illness or injury or because chemical changes within the body indicate that tissues are being damaged. When a nociceptor is turned on, a signal travels through the spinal cord to the brain, which recognizes the signal as pain.

When does normal acute pain become abnormal chronic pain?
When pain lasts a long time, it is called chronic pain. This type of pain is often caused by an illness or injury. Some doctors consider pain to be chronic when it lasts one month longer than expected, but the general medical definition of chronic pain is pain that has lasted for six months or longer.

Chronic pain can be one of two types: nociceptive and neuropathic. Each type differs based on what causes it, what it feels like, and what types of treatments may relieve it. Of the two, neuropathic pain can often be managed by a therapy called neurostimulation, also known as spinal cord stimulation (SCS). Dr. Hanna is experienced treating neuropathic pain using SCS and emerging experimental approaches such as IV Ketamine.

What increases your risk of developing a chronic pain condition? 

Risk factors are things that increase your chances of getting sick or having a problem. Risk factors for chronic pain include:

  • Aging. Older adults are more likely to have certain health problems that can lead to chronic pain, such as arthritis, diabetes, and shingles.
  • Certain health problems. These include:
    • Existing health conditions, such as fibromyalgia, shingles, arthritis, depression or anxiety disorders, or phantom limb pain.
    • Past health problems, such as joint injuries or past surgeries.
    • Overall general health. You may have a weakened immune system, which can lead to frequent infections or illness.
  • Lifestyle, such as not eating healthy foods, not exercising regularly,smoking, or having a drug or alcohol problem.

Other risk factors include stress, relationship problems, or a history of physical, sexual, or emotional abuse.

When should you see a doctor?
