or longer is called chronic. Pain is your body's way of telling you that
something is wrong. It's normal for you to have pain when you are injured or
ill. But pain that lasts for weeks, months, or years is not normal.
Chronic pain can occur anywhere in your body. It can range from being
mild and annoying to being so bad that it gets in the way of your daily
Anyone can get chronic pain. It's more common in older
adults, but it's not a normal part of aging. Older adults are more likely to
have long-term medical problems, such as
arthritis, which can lead to ongoing pain.
The cause of chronic
pain is not always clear. It may occur because brain chemicals that usually
stop pain after you get better from an illness or injury are not working right.

have tests to find out if a medical problem is causing the pain. Your doctor
may check for problems with your
nervous system and may order blood tests. He or she
may also ask you questions to check your mood and mental health and to see how
well you are able to think, reason, and remember.
In most cases, test results
are normal. This can make it hard to know the exact cause of the pain. But this
doesn't mean that your pain isn't real.
You can use home treatment for
mild pain or pain that you have now and then. Exercising, getting enough sleep,
and eating healthy foods may help reduce chronic pain.

Living with chronic pain:
The cause of
chronic pain is not clear.
When you have an injury or
illness, certain nerves send pain signals to your brain. With chronic pain,
these pain signals keep going for weeks, months, or even years after you recover.
Chronic pain can develop after a major injury or illness, such as a back injury
shingles, or it can happen without a known cause. It
is also possible that certain brain chemicals that usually suppress pain stop working the way they're supposed to.
Pain can affect:
You can have more than one kind of pain at the same time. For example, fibromyalgia can cause pain in muscles and nerves.
The symptoms of
chronic pain include:
Pain can lead to other problems, such as:
Whether your chronic pain develops after an injury or illness or on its own, the result is often the same: a cycle of sleeplessness, inactivity, irritability, depression, and more pain.
may be mild to severe. It may come back from time to time over
several weeks, months, or years. Exercise, good nutrition, regular massages, and
pain-relieving medicines—such as
nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin—may be enough to manage your symptoms.
On the other hand, you may have constant chronic pain that is severe and needs more than home treatment. Without treatment,
chronic pain syndrome can become disabling.
The lives of your family members, friends, or caregivers can
also be affected. The people you count on to help you may also need some
Family therapy or involvement in a caregiver support
program may help.

In your physical exam, your doctor will look for areas that are tender, weak, or numb. The doctor will also check for health problems that contribute to chronic pain, such as:

This includes improving your sleep and your coping skills and reducing
stress so you can return to your regular activities.

Medicines can often help control
chronic pain. In some
cases, it may take several weeks for the medicine to work.
Medicine may work best when it's used along with other types of treatment, such as physical therapy and
counseling, to address the different causes of chronic pain.
Sometimes a medicine loses some or all of its ability to work
when it is used daily over a long period of time. This is because your body develops a
tolerance to it.
You will likely start with medicines that cause the fewest
side effects (such as
acetaminophen). The dose will be
increased or the medicines will be changed as needed.
A variety of creams, gels, sprays, and patches may be used to relieve chronic pain, including:
Injected medicines—shots—may be used to treat chronic pain, including:
Surgery for chronic pain isn't common. It's usually considered only
after other treatments have failed or if it is considered medically necessary.
Surgery may provide pain relief, but it also may permanently
damage your ability to perceive other sensations, such as light touch and
temperature changes. It can also cause a different pain to occur.
Implanted pain control systems involve inserting devices under your skin or elsewhere in your body. The devices use medicine, electric current, heat, or chemicals to numb or block pain.
Decompression is a type of surgery used for nerve pain, such as from trigeminal neuralgia. The doctor cuts open your skin and then tries to move away blood vessels or other body structures that are pressing on nerves and causing pain.
For back pain, physical therapy, osteopathic care, or chiropractic care usually includes spinal manipulation, which is a kind of manual therapy. It involves working on the head, shoulders, neck, back, or hips. It can range from massage and slow pressing to a quick thrust. Your care provider may also use hot
and cold therapy to relieve pain.
You may also learn
range-of-motion exercises to maintain strength,
flexibility, and mobility.
Transcutaneous electrical nerve stimulation (TENS) applies brief pulses of electricity to nerve endings in the
skin to relieve chronic pain.
It's common to respond to chronic
pain with feelings of frustration, depression,
anxiety, fear, and even anger. These feelings can make
it tough to conquer chronic pain, especially if you use alcohol or drugs to
manage your symptoms.

treatments such as
