Quick facts and meaning
According to Healcure.org, “Armpit pain refers to the aching, throbbing, stinging, twinging, and soreness, tenderness or general physical discomfort in and around your armpit or underarm area.”
This pain in the armpit could be present alongside some very painful lumps in your armpit or without any lumps.
In addition, this pain can be experienced by male and female, children and adults but some causes may be more specific to women or men.
On location, the pain could be on the right left or the right armpit and can extend to nearby parts such as chest, shoulder, breast and other parts.
Finally, it can be mild, chronic or sharp shooting depending on the causes. Let us now look at the common causes of pain in armpit.
There are many potential reasons as to why you may experience pain in the armpit. Therefore, in this section, we are going give you the most common triggers of ache and pain under armpit.
1. Armpit lymph node pain (Lymphadenitis)
Axillary lymph nodes pain or lymphadenitis is the inflammation, swelling or enlargement of the lymph nodes or glands. This condition takes place when your body responds to bacterial, fungal, or viral infections.
Such pain is usually experienced in area near the infected or inflamed site. This results to swollen lymph node that can lead to sharp shooting pain in armpit. “Other health conditions that may cause lymph node swelling include autoimmune disorder rheumatoid arthritis or even cancer.”[Medhealthdaily.com]
2. Hidradenitis suppurativa
One of the major cause of axillary pain with lump is inflamed or infected sweat glands and hair follicles. The pain can also be experienced in buttocks, groin or below the breast among other parts.
This occur when the skin pores are clogged with excess sebum and dead skin cells. This will lead to bacterial infection hence resulting to pimples and acne. Some deep types of acne such as nodules and cysts can cause severe pain when they occur in your armpit. Cyst is a large pimple that occurs alongside scarring and severe itching.
3. Muscle Strain
Have you ever experienced pain under armpit after picking something, certain sleeping positions or exercising without warming up first? Now this could be due to strained or pulled muscles.
The major muscles that commonly lead to this condition is the pectoralis in your chest. Remedies could involve the application cold and warm compresses, anti-inflammatory drugs among others, which we are going to discuss later in this article.
4. Breast cancer
Pain under the armpit could also be due to breast cancer, a common health condition among women. A woman suffering from breast cancer can suffer symptoms such as nipple discharges, changes in the size, shape and appearance of her breast, breast skin dimpling, and rash around the nipples.
Breast cancer can also occur alongside lymphoma a condition that also trigger pain under armpits. Related symptoms include swollen legs, neck and groin lymph nodes, abrupt weight loss, cough, fever, appetite loss, intense sweating, fatigue and more.
5. Peripheral artery disease
Due to some medical conditions, the arteries in your arms and legs (with exception to those arteries found in near heart and brain) may become narrower or obstructed. When this happens, there will be reduced blood flow in the concerned arteries. This can therefore result to a sharp, shooting pain underarm as well as on other parts.
6. Pregnancy and breastfeeding
Some women have also reported cases of experiencing pain in armpit during pregnancy and breastfeeding. During early pregnancies, women can develop armpit pain accompanied with breast tendering. This condition is normally associated with intense hormonal changes experienced during this period.
On the other side, armpit pain during breastfeeding can be experienced when a mother produce a lot of milk than she can expel. Other factors that can cause ache armpit during breastfeeding include wrong nursing bra, breast infections and bad breastfeeding positions.
7. Shingles (Herpes zoster)
Shingles otherwise known as Herpes zoster, are a very painful medical condition that can be experienced anywhere in your body but it is common on the left and the right side of the body stem. It begins when virus attack the nerves and hence results to painful rashes in the body. This condition develop close to you armpit, then you may experience a very thrilling armpit pain.
There are numerous shingle symptoms, which some can be mild while others may be severe. They include pain, burning sensation, red rash, fluid-filled blisters, fever and more.
8. Brachial plexus injuries
First, understand this, “The brachial plexus is a network of nerves located in the neck and shoulder, which also course through the armpit” [Livestrong.com]. Pressure, trauma or stretching can damage this network.
Sometimes when you force your head or neck away from the affected shoulder in the opposite direction, you can have traction (brachial plexus injury). This may force the nerves to detach from their roots in the neck. This will lead to pain underarm, numbness among other symptoms.
9. Shoulder Dislocation
Pain under the armpit can also be caused by a shoulder dislocation. Your shoulder is the most susceptible part to dislocation since it has the most mobile joint. Shoulder locations means that the upper arm bone fully slips out of your shoulder socket.
Common signs and symptoms are numbness, weakness, swelling as well as bruising in the underarm.
10. Peripheral artery disease (PAD)
This is a condition where by small arteries in your arms and legs narrows leading less oxygenated blood to reach the muscles and limb tissues. This can lead to sharp pain your armpits. “Oxygen-starved muscles hurt” [Healthline.com]
1) Skin conditions, armpit hair removal and allergic reactions
Skin conditions can as well lead to painful armpit. Furthermore, some activities like waxing or shaving underarm usually leads to irritations that can lead to lumps in the affected body areas.
In addition, some deodorants or laundry detergents can also trigger allergic reactions (contact dermatitis). Applications of some cosmetics can also lead to skin bumps. When all these factors occurs in your armpit, definitely you can experience some pain in your armpit.

On Left armpit
It is possible to experience pain in both armpits (bilateral underarm pain) but usually, people are very concerned to left armpit pain than right armpit pain. This is because your heart is located in the left side of your chest. This make them always take up that pain in left armpit is due to heart disorders. This can be very true but there can be also other causes i.e. those we had discussed before.
Many of the armpit pain symptoms and causes are similar to both left and right armpit but causes or rather symptoms such as shortness of breath, jaw pain, headache, toothache, sweating, heartburn, racing heart, upper neck pain, dizziness, anxiety and general malaise etc. can be due to heart problem.
Some symptoms like armpit pain during lifting objects or weights could be due to disorder of joints or muscles and not heart problems. You doctor can also help to determine whether your left armpit pain is due to heart problem or not.
Stabbing, shooting or sharp pain
In some cases, one may develop sudden sharp stabbing pain in armpit. Such pain resembles electric pulse and it can be throbbing! Such sharp shooting pain in armpit can occur in your right or left armpit and is a condition can be experienced in both male and female. It can then spread to your shoulder, down arm as well as other places. Below are the common causes of sharp shooting armpit pain:

- Cerebrovascular accident
- Swollen armpit lymph node
- Angina, chest pain and pregnancy
With or without lumps
Pain in armpit can be present with or without a lump. Armpit pains with no lump are usually sudden and may last for shorter time as compared to painful armpit with lump. Some underarm pain with no lump can also last for even a week for instance, those triggered by shoulder dislocation or breastfeeding.
Some other causes of armpit pain without a lump are pregnancy, peripheral artery diseases, Lymphadenitis, muscles strain, brachial plexus injury or heartburn among others.
On the other hand, pain in armpit with lumps may be due to viral, bacterial and fungal infections, Hidradenitis, cancer, allergies, waxing and shaving, and many more.
We should make these clear, underarm pain with lump can last for longer period; it can be severe and require medical attention.
I don’t tend to mean that all underarm pain with no lumps are mild, or do not last longer or is simple to treat. I just want you to get it clear that painful lumps may need a lot of oral and topical treatment than painful armpit without lump. There severity in the two situations will depend with the primary causes.
NOTE: it is also possible to have painless lump under armpit or painless armpit with lump
Pain under armpit and breast
