It's
a common problem in our country that your legs and feet suddenly become red or
develop red rashes. Within three or four days, the legs become completely red,
accompanied by swelling and pain. If more days pass and proper treatment is
neglected, the redness and swelling can lead to the formation of small and
large blisters. If this neglect continues, the blisters on leg can burst in
multiple places, oozing yellowish fluid. This negligence can lead to serious
damage to the legs and feet. Therefore, it's important for you and your family
to understand the causes of this problem and learn about the proper treatment.
Who arecommonly suffering from this
problem?
Redness in the legs and feet is medically known as
"cellulitis." This problem is more common in people who everyday
spend hours sitting in their shops or other establishments. Nowadays, people
working in corporate offices and call centresfor years also suffer from redness
or rashes in their legs and feet. Even those who gain excessive weight are not
spared from the problem of sudden redness in their legs. Those even in young
age who do not regularly walk at least five to six kilometres a day are also
not immune to the problem of sudden redness in their legs. Redness in the legs
is also common among diabetic patients.
What are the causes of sudden redness in
the legs?
The most common cause is leg vein disease. Amongvein
diseases of legs , the first is CVI (chronic venous insufficiency). The second
is blockage or constriction in the leg veins. Both types of leg vein disease
cause persistent swelling in the legs and feet. If not treated in time, the
swelling in the legs becomes larger and larger, and red rashes appear in the
end. In this condition if a nail or a thorn pricks your swollen foot or leg,
the skin of the leg turns red rapidly. Sometimes, repeated scratching in a
swollen leg exacerbates redness.
Diabetes and obesity also play a
significant role
The second major cause is diabetes. Even a minor
injury to the foot or leg, or a thorn prick, or a minor cut or burn, increases
the likelihood of the leg turning red and swollen. A black crust or a pustule
persisting for a few days on the leg may lead to redness of leg.
The third major cause is obesity. Due to
excess fat in the leg, even a minor injury or scratch increases the risk of
infection and rapid spread. The leg turns red very quickly.
What to do if your leg suddenly turns
red?
If your leg is red and swollen, don't sit idle.
Consult an experienced vascular surgeon immediately. If you delay, blisters may
also appear along with the red swelling. And if this negligence continues, pus
will begin to accumulate in the leg along with redness and swelling, leading to
a serious condition.
Get Necessary Tests Done
If there is redness and swelling in the leg,
arterial Doppler and venous Doppler tests of both the legs are essential. If
necessary, an MRI of the leg is also required. Sometimes, angiography of the
leg also become necessary. In addition, some special blood tests are required.
Treatment Methods
your
vascular surgeon will determine the treatment plan after examining the leg. The
first step is to reduce the infection and swelling in the leg. It is crucial to
administer antibiotics through a vein [intravenous] to prevent the formation of
pus. Special dressings are required. After the redness in the leg subsides, it
is crucial to treat the underlying cause. In most cases, the veins in the leg
need to be treated, with the use of laser or RFA techniques being the most
common. In some cases, angioplasty of the leg veins may also be required. In a
diabetic, an angioplasty and stenting may require.
How to avoid redness and swelling in the
legs
First, control your weight and try to achieve the
desired weight according to your height. Walk five to six kilometres regularly
every day. Never sit or stand for more than an hour at a stretch. Always take a
five-minute break after every hour and take a walk during that time. Do leg
exercises that require lifting of legs. Keep diabetes under control.
