The hairline's skin on the back of the neck comes into contact with galore property that can irritate it, including residual detergent on clothing items, shampoo, sweat and hair care products. This skin area is also subject to hair and apparel friction. As a result, lumps, bumps and other skin problems are relatively common here.

A lump can be appalling, especially if it's not in sight. Nevertheless, a variety of conditions can cause a swollen lump on the back of the neck, including benign causes, such as skin disease and irritation. Sometimes one cause leads to another. For example, a boil on the back of the neck can cause the nodes of the liquid body substance to swell.

The most common causes of a lump on the neck are the following:

Swollen nodes of liquid body substance

The nodes of the liquid body substance are the drain system of the body. They help the immune system get rid of bacteria, viruses and dead cells. Liquid body substance nodes sometimes swell, especially when the body is fighting an infection.

Several liquid body substance nodes run on either side of the spine on the back of the neck. Besides, there are nodes of liquid body substance behind each ear. A tender lump that is about the size of a marble and moves slightly when a person touches it can be a swollen liquid body substance node.

Sometimes nodes of liquid body substance swell when an infection is near. A swollen liquid body substance node in the neck might therefore be a sign of an ear infection or a septic cyst. Apart from swelling, liquid body substance nodes can swell for no apparent reason. As long as the swelling disappears, there is no reason to worry.

Although it is rare, nodes of swollen liquid body substance can sometimes signal a more serious problem, as much as cancer. People should see a doctor if the swelling does not disappear after a couple of weeks.


Acne can cause lumps and swellings on the back of the neck, including blackheads, pimples, and deep cystic skin disease.

Acne develops when pores are blocked by sweat, bacterium, and oil. Although secretion changes often trigger skin disease during adolescence, it may appear at any age.

The neck is a common skin disease site. Hair care products, sweat and clothing items can all irritate the back of the neck, exacerbating skin disease.

A wide variety of over - the-counter (OTC) remedies can help with switching shampoos, keeping the neck clean and dry, and keeping the hair off the neck.

If skin disease is severe, very painful, or fails to respond to home remedies, a skin doctor may order a stronger medication.


A greasy cyst is a nodule that contains the ceratin of the macromolecule under the skin. These cysts can grow very big. Most are painless, but they may match large pimples if they become septic. Cysts may come and go, or they may grow larger continuously.

Some kysts come to a head or ooze when a person squeezes them. Nevertheless, pop a cyst won't cure it, and it can cause an infection. In most cases, a doctor may use a simple procedure to remove a cyst in their office.

If the cyst is painful or red, it is important to see a doctor as it is a sign of infection. Apart from that, warm compresses and OTC pain medication can help.


A powerful red and painful bump is a boil. Boils are local infections, which means that the boil contains an infection, but not the surrounding skin. Cysts, skin disease, and hair follicles that are blocked can become septic and turn into boils.

Squeezing a boil can cause the infection to worsen or spread. Instead, people should try to apply warm compresses and keep the area clean.

If fever develops or if the boil is very painful or does not go away alone in a few years, a person should see a doctor. The doctor may be able to drain the boil or order antibiotics.


Moles appear during childhood in most cases, but new moles can grow at any age. If the lump feels fleshy and is on the skin rather than under it or in the muscle, it may be a mole.

Moles themselves are not a problem, but some moles may become cancerous. A person can use a mirror to look at the mole or ask someone else to check it.

Use the form below to check for signs of skin cancer:

  • A: asymmetrical mole
  • B: uneven or irregular border
  • C: uneven color or unusual sunglasses, so much as blue and red
  • D: diameter lesser than 6 millimeters (about the size of a pencil eraser)
  • E: evolving and ever-changing over time

Anyone concerned about their moles should consider programming an annual mole check with a skin doctor to make sure they're all healthy.

Allergic reactions and skin irritation

Many substances can irritate the neck's back.

Shampoo, hair care products, clothing item detergent, and sunblock may cause skin irritation or allergic reactions. Besides, friction from clothing items sometimes irritates the neck and causes a rash.

If the lump is small and itchy or the neck has dry patches, this could indicate annoyed skin or an allergic reaction.

A person may find that it helps to change detergents, keep the neck clean, keep the hair off the neck, and reduce the number of products they use on the skin and hair.

If these actions are not effective, a doctor may want to test for allergies and examine the rash to ensure that it was not caused by anything else.

Muscle knots

Knots can be formed by injured or tense muscles. These tight bands of muscle tissue can be as small as a pea or as large as a baseball. In most cases, they are only palpable under the skin and will not cause a visible lump or bump above the skin.

The neck is a common site of muscle pain and tension. Disbursement consecutive years being round-backed over a table and looking at a computer can irritate the muscles that connect the head to the hairline neck. Muscle knots, besides being called myofascial trigger points, are a sign that the muscles are tense. They do not, however, indicate a serious health problem.

A lump is likely to be a knot of the muscle if:

  • It's in the muscle band rather than the bone or the skin.
  • Pushing on it causes muscle pain or tension in either the knot or the surrounding area

Massage with muscle knots can help. Smooth neck stretches, frequent breaks, and good posture can also be beneficial and can prevent muscle knots from forming.


It's easy for a person to panic if they feel a lump on the back of the neck. Nevertheless, most lumps are relatively harmless and very few are real emergencies. If the lump does not hurt and there are no other symptoms, it is usually okay to wait a few years to see a doctor. If the bump does not go away, a doctor should be seen by a person.

Even if the cause is something serious, as much as an infection or cancer, early treatment significantly increases the likeliness of a positive outcome. People should not allow fear and anxiety to dissuade them from seeking medical attention.
