Erythema nodosumErythema nodosum is an inflammatory condition
Erythema nodosum is an inflammatory condition affecting the skin.
Painful, red and tender lumps appear, most commonly over the lower
legs (shins), although other parts of the body may be affected.
As the lumps progress, they become darker, often look bruised
and sometimes peel. Around half of those affected will feel tired
or unwell, and may experience fever or sore joints. Erythema nodosum
mainly affects young adults, and women more commonly than men.
The appearance of erythema nodosum may indicate
another problem
The appearance of erythema nodosum often indicates the presence
of another problem, such as infection (Streptococcal bacterial
infection of the throat is one of the most common causes), reaction
to a medicine (particularly antibiotics or the oral contraceptive
pill) or other medical condition (such as sarcoid, an inflammatory
condition of unknown cause) or even during pregnancy. Rare causes
include inflammatory bowel disease, Behcet's disease and lymphoma.
Even herbal remedies like Echinacea have been associated with
this condition. For this reason, special tests like blood tests,
chest X-ray or even a biopsy of the rash may sometimes be required.
Erythema nodosum is usually transient
Most cases resolve within a few months and rarely return. Long-term
complications or scarring are extremely unlikely. The aim of treatment
is therefore to keep patients comfortable until symptoms resolve
with time.
Management of erythema nodosum
Erythema nodosum is painful and often results in leg swelling.
Bed rest, simple painkillers and cold packs may be all that is
required. Sometimes, severe pain, fatigue and sore joints demand
more aggressive treatment, such as cortisone tablets, potassium
iodide or other medications. Such treatments should only be given
under the close supervision of your medical practitioner.
