The toes burn and tingle and sharp pains shoot into your legs. The
bed sheets feel uncomfortable on the feet as you toss and turn, trying
to get some rest. Your feet felt numb throughout the day, but now feel
like they are on fire. Nothing seems to help as you watch the hours on
the clock pass by, hoping to fall asleep.
Burning, numbness, tingling, hot and cold sensations, shooting and
electrical pain are common sensations felt at rest in painful peripheral
neuropathy. Neuropathy is an abnormality of the nervous system. There
are many different types of neuropathy, but the most common neuropathy
effecting diabetics is peripheral neuropathy.
Diabetic neuropathy is described as a loss of sensation that starts
in the tips of the toes and gradually works its way up the legs, and in
severe case into the hands. It is sometimes referred to as a stocking
glove neuropathy because it progresses as if one was pulling on a
stocking.
Sixty percent of diabetics have some type of neuropathy in their
feet. Five percent of diabetics will experience painful diabetic
neuropathy and the incidence increases with age. Over 45% of individuals
who have had diabetes for over 25 years will experience some symptoms of
painful diabetic neuropathy.
The cause of diabetic neuropathy is not clearly understood. Many
believe that the damage to the small vessels surrounding the nerves,
from the diabetes, causes damage to the nerves. Others believe the
increase in blood sugar causes damage to the nerves. Despite the
different theories, studies have shown better blood sugar control helps
prevent progression of the neuropathy.
There are currently no treatments to help reverse diabetic
neuropathy. There are no treatments which help reduce the numbness. But,
there are many treatments to help decrease the pain associated with the
neuropathy.
Your doctor may prescribe medications to help with the pain. There
are many options, but until recently none were FDA approved for the
treatment of painful neuropathy. Cymbalta®, duloxetine HCl, was recently
approved by the FDA in September of 2004 for use in diabetic peripheral
neuropathy at doses of 60 and 120 mg per day. This is the first drug
approved for this use. Similar medications, like amitriptyline,
desipramine and nortriptyline, have been used to help decrease pain and
help with sleep.
Gabapentin, also known as Neurontin®, has been a successful treatment
for painful diabetic neuropathy. Neurontin® was originally approved by
the FDA for adjunctive use in seizures, but the benefits of this drug
for other conditions, like neuropathy, soon became known. The
manufacturers of Neurontin® were caught up in a controversy regarding
their marketing tactics for this off label use. Many physicians still
use this drug despite the controversy. Tegretol and Dilantin, common
seizure medications, can be used in more severe cases. New treatments
include lidocaine 5% cream, acetyl-L-canitine, nerve growth factor and
Annodyne ®, infrared therapy.
To help treat painful peripheral neuropathy without prescription
medications, consider the following tips:
1. Keep your blood sugar in control: Studies have shown that when
blood sugars remain high, or roller coaster from high to low, peripheral
neuropathy will worsen.
2. Exercise. This is probably the last thing you wanted to hear.
Exercise helps increase circulation and stimulates the growth of new
vessels which help slow the progression of the neuropathy. Exercising
also helps to increase your pain threshold and to provide a distraction
from the nerve pain in your feet.
3. Eat healthy. Besides helping to control your blood sugar, eating a
wide variety of fruits and vegetables will add anti-oxidants to your
diet. Anti-oxidants will combat the damaging oxidative effects glucose
has on your nerves. In particular, try dark-green, leafy vegetables,
yellow, orange, and red fruits and vegetables, citrus fruits and
tomatoes.
4. Try red pepper powder. Capsaicin is the active ingredient in chile
peppers. When applied to the feet it acts as a counter-irritant and can
help decrease neuropathic pain. Capsaicin can be purchased at your local
drug store. If you cannot afford capsaicin, try mixing 1 tablespoon of
dry chile powder with 2 tablespoons of baby powder. Place the mixture in
a sock and use the socks at night.
5. Try alpha lipoic acid. ALA is an effective anti-oxidant that has
been shown to relieve pain associated with neuropathy in multiple
studies. To help relieve pain, the dose must be at least 600mg a day. It
is advisable to start with a lower dose, as higher doses can cause
nausea, stomach upset, fatigue, insomnia and can lower blood sugar. In
general, ALA is a safe supplement.
6. Try gamma linolenic acid. GLA is an essential fatty acid found in
evening primrose oil. Most of the studies have shown modest results, but
the possibilities are still encouraging. Take 360mg/day. Many
indications require higher dosages, but side effects with long term use
at higher doses may include inflammation, thrombosis (blood clots), or
decreased immune system functioning.
Treating painful diabetic peripheral neuropathy is very difficult and
many of the above mentioned therapies should be tried and combined.
Don't expect any "cures" and make sure you give each therapy a chance to
work.
