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.
