Several different types of
pain may occur in people with HIV disease or AIDS. The pain may
be directly due to the virus or indirectly from the accompanying
infections or from treatment. The HIV virus may irritate the nerves
and produce neuropathic or nerve pain. Symptoms may include burning,
numbness and pins-and-needles sensation of the hands and feet. Nerve
pain may result from dietary deficiency, drug therapy (anti-viral
medications, Dilantin, INH), chemotherapy, radiotherapy and surgery.
Other types of pain include abdominal pain, headache, mouth pain,
skin pain and joint pain. Abdominal pain is often accompanied by
diarrhea and may be due to infections like cryptosporidosis or MAI
(Mycobacterium avium-intracellulare) that can lead to swelling and
obstruction. Tension headache or migraine may occur especially (up
to 40% of the time) during AZT therapy. If T-cell counts are less
than 200, headache may be a warning sign of HIV encephalitis (inflammation
of the brain), toxoplasmosis or lymphoma. Pain in HIV disease or
AIDS may be from rheumatoid conditions such as arthritis, polymyositis
(inflammation of the muscles), vasculitis (inflammation of the blood
vessels) or AZT myopathy (muscle inflammation caused by AZT). Mouth
pain may occur from ulcers due to yeast infection. Skin pain may
be from infection with Kaposi's sarcoma or shingles (herpes zoster).
Regular check-ups with your
doctor will help you to get access to the latest anti-viral drugs
(including the new protease inhibitors) and keep your disease in
check. If you have any infection e.g. from yeast you should get
treatment early. The best prevention is to take all your medications
regularly. These medications will help keep up your T-cell counts
and prevent complications.
The various treatments depend
on the severity and cause of the pain. When pain is slight, you
may take pain relievers, such as Tylenol or Motrin. Apply wet or
dry heat to painful muscles and joints or rub over-the-counter ointments,
rubs and sprays such as Eucalypta Mint or Ben-Gay. A new ointment
called Zostrix (Capsaicin) may help by decreasing the amount of
substance P that sends pain signals to the brain. Zostrix is the
burning ingredient in red-hot chili peppers. The ointment itself
may give you a funny burning sensation that lasts the initial couple
of days. Wear rubber gloves when you apply it and keep it out of
your eyes. Anesthetic ointments such as Lidocaine or an anti-itch
cream called Zonalon (Doxepin) may also be used to numb the area
of pain. Recently many patients have experienced significant relief
from burning skin or nerve pain by applying specially compounded
ointments containing various combinations of Ketamine, DMSO, Neurontin,
Ketoprofen or Clonidine. Relief with Ketamine ointment has been
comparable or even superior to that obtained from sympathetic blocks.
With more severe pain, you will require stronger pain relievers
such as Codeine or Ultram. These are short acting and should be
taken every four to six hours as prescribed by your doctor. These
medications may be combined with other medications such as anti-
inflammatory drugs like Motrin, antidepressant drugs like Paxil.
These other medications may significantly increase the pain relief.
The antidepressant medication may also help in improving your moods.
If your pain returns before the next dose of pain killers is due,
you will need a long-acting strong pain killer to provide background
pain relief while still using the short-acting pain killers for
any breakthrough pain. In such case your physician may prescribe
long acting morphine tablets to be taken one to two times daily
and short acting Ultram or Percocet to be taken every four to six
hours as needed.
The long acting painkillers need to be taken regularly even when
you feel you do not have a lot of pain. A new long acting painkiller
your doctor may want to use is a skin patch called Duragesic. This
is a very strong pain killer (stronger than morphine) that you wear
as a patch over your chest or back. It releases medication slowly
through the skin and should be replaced every two to three days.
Your short-acting painkillers may be used in-between. Medications
used in special situations include intravenous (IV) or intramuscular
(IM) injections of painkillers. These are often used in a hospital
or nursing home. There are new machines for hospital and home use
called PCA (Patient Controlled Analgesia) pumps. These machines
have a user button which when pressed injects a small amount of
the pain killer medication through the IV tubing.
After an injection, the PCA pump will not deliver medication for
a programmed (lockout) period of time e.g. 10 minutes - even if
the button is pressed. After the lockout time, the PCA pump will
deliver medication with the next press of the button. The PCA pump
reduces pain medication side effects by allowing you to give yourself
frequent small doses rather than occasional big doses. For skin
pain, anesthetic ointments such as Lidocaine or an anti-itch cream
called Zonalon (Doxepin) may be used to numb the area of pain. If
you have nerve pain, anticonvulsant medications e.g. Tegretol, Dilantin
or Neurontin may help ease the pain. Take the medications regularly.
Some of these medications may decrease the production of blood cells
so your physician may have to check your blood every few weeks.
Occasionally some of these medications may produce a skin rash.
Other medications that are used in treating nerve pain include antidepressants
like Paxil, St. John's Wort and strong pain relievers like Vicodin
or Oxycontin. Dextromethorphan is a morphine like drug that is used
in cough medications to reduce coughing. It does not produce any
pain relief by itself. However it prevents development of tolerance
to the pain relieving effects of opioids. When used in combination
with opioids dextromethorphan may enable a decrease of up to 50%
in the amount of opioid required, thus enabling pain relief with
fewer side effects e.g. drowsiness. Dextromethorphan has to be prepared
in a pure form by a compounding pharmacist as it is only available
commercially combined with other ingredients such as antihistamines
in cough syrups. In addition to medications, nerve block with local
anesthetic, steroids or glycerol may provide good long-term relief.
A side effect of these procedures may be prolonged numbness in the
area of pain. Before any procedure your doctor should explain the
risks and benefits to you. Local anesthetics used alone or combined
with opioids or clonidine may be injected directly into the back
using a small tube called an epidural or intrathecal catheter. This
may provide long lasting pain relief because the medication acts
right at the site of the pain receptors in the spinal cord. When
a tumor or infectious mass pressing on the nerves, bone or tissue
causes pain, removing as much of the tumor with surgery may relieve
the pain. Surgery may sometimes be required to remove painful nerves.
The tumor size may also be reduced with chemotherapy or radiation
therapy. Acupuncture and electrical stimulation therapies are sometimes
helpful by increasing the body's production of natural pain killing
hormones. Alternative HIV/AIDS therapies include special diets,
macrobiotics, megavitamin therapies, herbal, detoxification and
heat treatments. Gather as much information as you can and be wary
of treatments that sound too good to be true. Mind-body therapies
help in pain control by promoting relaxation, hope, control and
optimism. These include relaxation training, controlled breathing,
meditation, repetitive prayer, visualization, and imagery/distraction
techniques, yoga and music therapy. Your doctor may also help you
learn to relax by using biofeedback, behavioral modification or
hypnosis. Join support groups. These are helpful as they enable
you talk to others who have the same problems. You will be able
to share your feelings and practice stress reduction and pain control
techniques. If you are depressed you may need antidepressant medication
and counseling.
Call your Doctor
and stop your medications if you have a reaction to any of your
medications.
