Lymph nodes back of neck3/11/2023 Swollen glands may accompany a sore throat - which can cause painful swallowing and may feel like there is a soreness, discomfort, pain, or scratchiness in the throat - depending on the cause of the pain. The lump may or may not be tender or painful, and you may feel one lump or several. Some swollen lymph nodes are only slightly noticeable. RELATED: What Does Arthritis Pain Feel Like?Ī lump that you see or feel, especially in your neck, armpit, or groin, can be a symptom of lymphadenopathy. Sometimes the swelling is localized (in only one place in the body), and sometimes it's diffuse (throughout the body). When lymph nodes become swollen or enlarged, doctors refer to the condition as lymphadenopathy. In a nutshell, lymph nodes help keep you healthy. Lymph nodes (also known as glands) filter waste out of lymph, a sticky, clear fluid that contains white blood cells, which help fight infection. Depending on the tests the results may take from a few hours to several days to be processed.You have hundreds of lymph nodes throughout your body, and large clusters of them in three particular areas: your neck, your armpits, and your groin. Anaesthetic cream can be used first if requested but is not generally required. A very small needle is used to draw a few mls of blood from a vein just under the skin. How?ĭespite a large number of tests being requested, usually only one sample of blood is required. There are numerous tests that can be performed on a single blood sample to diagnose many diseases. Occasionally the sample may be inadequate and a repeat sample may be required. This means the result may take several days to come back. The sample has to be processed and then carefully examined by a doctor called a cytologist afterwards. A small amount of bleeding can occur briefly afterwards and occasionally some tenderness or bruising can last a few days. The needle may need to be moved in and out of the lump 3-4 times to obtain an adequate sample and is then withdrawn from the skin. Local anaesthetic is usually injected to numb the skin, and then a thin needle is inserted through the skin into the lump. How?įNA is often performed with ultrasound guidance to ensure that an accurate sample is taken. FNA can often distinguish between benign and malignant neck lumps and cysts. Neck and thyroid lumps may be easily palpated and seen on scans, but frequently it is necessary to take a sample of cells from the lump to determine its exact nature. Some patients find this enclosed experience unpleasant, which has resulted in the development of so-called “open scanners”. The patient lies still on a couch with their head in a metal tube. The commonest indication for an MRI scan is parotid or tongue tumours and sinus or skull base tumours. This scanned information is then used to construct images of specific parts of the body. Instead it uses a powerful magnetic field to align tissue atoms, and then uses radiofrequency fields to change and record their alignment. MRI does not use ionising radiation unlike CT or traditional X-rays. It provides good contrast between the different types of tissue, which is a major advantage over CT. Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to study internal soft tissue structures in detail. The scanning technique involves lying still with the head in a medical “hair-dryer” capsule for approximately 20 minutes. Airway problems and head and neck cancers are well demonstrated on CT scanning. A temporal bone CT scan will therefore show details of sinus and jaw bone problems. The main advantage over MRI scanning is that it demonstrates bone as well as soft tissue features. It provides important diagnostic information in various anatomical planes. On occasions the doctor may decide that a fine needle aspiration is necessary to obtain more information (see below).Ĭomputed tomography (CT) is a medical imaging method using X-ray tomography created by computer processing. A gel is placed onto the skin and a doctor moves the probe across the skin while looking at the images on a monitor. The scan is similar to pregnancy scans and is entirely painless. The cause of the lump and the site it has arisen from can usually be identified. Ultrasound is an excellent way of investigating neck lumps and looking at the thyroid gland. The possible causes include infections (viruses, bacteria or others), tuberculosis, lymphoma and cancers of the head and neck. If nodes are persistently enlarged you should consult a doctor. The site of the swellings indicates the area drained by the nodes and is a guide to the source. Transient enlargement for 2-3 days may occur with an infection in the head and neck such as tonsillitis, skin or ear infections.
