Lichen planus is a non-infectious skin condition that causes an itchy, bumpy rash on the skin, scalp, or in the mouth. The cause is unknown, but treatments such as corticosteroid creams and antihistamines can help reduce inflammation and itching. Recovery can take several years, but most people will eventually recover and not get it again. Soaking in oatmeal or cornstarch and wearing comfortable clothing can also provide relief.

Lichen planus refers to a condition that can cause an itchy, bumpy rash on the skin or sometimes on the scalp or in the mouth. This is not an infectious rash, which is a good thing, but the painful itch can be difficult to tolerate, and the condition can take several years to fully resolve. Others have inflammation that goes away sooner, within a few months.

Not much is known about the causes of lichen planus. Some people who get it have scarring on their livers or have hepatitis C, but many people who get it have normal, healthy livers, making this connection weak. It usually affects middle-aged people the most, but people of other ages can get it as well.

Symptoms of lichen planus include rashes that may cover the arms, legs, trunk, genitals, or scalp. The rash is flat on top, but itches painfully and can be any color from pink to red to purple. If the scalp is involved, hair loss is common. The rash is also known to burn if it is on mucous membranes, such as parts of the genitals or in the mouth. When bumps are present in the mouth, they usually become open sores and some people notice a metallic feeling in the mouth or dry mouth.

If people have a rash like this and suspect lichen planus, it’s worth seeing a doctor. While most treatments don’t cure the disease immediately, they can reduce inflammation and help people feel more comfortable. Typical treatments for lichen planus may include corticosteroid creams that help reduce itching. Some people may need to take an oral steroid to help reduce inflammation more effectively. Medications such as antihistamines may also be recommended to minimize itching.

As mentioned, it can take a while for lichen planus to clear up and some people come back again, just as it seems to go away. Oral forms of the condition are usually the toughest and take the longest to heal. Eventually most people recover from this painful skin condition and most will never get it again.

It can be difficult while lichen planus is present because the constant itching sure is crazy. In addition to using any cream recommended by a doctor, many people find they are made more comfortable by soaking in oatmeal or cornstarch and wearing comfortable, breathable clothing made of natural fibers. Doctors might also recommend other medications if the condition creates problems with sleeping or concentrating. Sometimes the use of tranquilizers or simply the use of antihistamines can help.
