The most characteristic symptom of the disease is a stripe of blisters, which are filled with fluid. They may break, which is really painful. Apart from that, you may also observe an itchy rash or a kind of a burning sensation on the skin, which can be more sensitive to touch as well.
In general, shingles is not considered to be dangerous on condition that your immune system works well. Therefore, it’s potentially risky for children and older people as their immune system is often weakened. Consult your doctor if you suffer from additional symptoms such as fatigue, headaches, fever, or when the rash spreads to your eyes area.
12. Breast Cancer
Pain in your left armpit may also be a potential symptom of breast cancer. You need to be alarmed especially if you’ve also noticed that one of your breasts looks slightly different. It may be a change in the shape or size of the breast, you may feel some bump in it or that your nipple suddenly got inverted or some liquid comes up.
Even if you feel something in your breast, you don’t need to panic as most changes are just cysts or fatty growths, which are benign. What’s more, as your armpit is usually warm and wet, it’ s good place for cysts development. Luckily, you can have them easily removed or they just go away on their own.
Remember that a breast cancer is often a matter of genetics. Therefore, if any of your relatives has suffered from it, you can’t ignore even the slightest change you notice in your breast. Actually, you should control your breasts even if you don’t see anything suspicious.
Other factors which may potentially lead to a breast cancer include hormonal problems, your lifestyle, and environment you live in. Those are just theories, though, which have not been firmly proved.
A breast cancer often starts in breast tissues, cells, or milk-producing ducts, and at the beginning it’s just a small lump under your skin. Remember that the earlier you examine it, the higher probability that it’s nothing serious. Also, be aware that breast cancer may also appear in men.
13. Connective Tissues Disorders
If you’ve been suffering from unexplained pain in left armpit, it might be the consequence of damage or degeneration of your connective tissue. You won’t observe any bumps there, but you may have some moving difficulties.
You won’t manage to deal with the problem on your own so if your pain lasts more than a few days, consult your doctor on this matter.
14. Anxiety and Depression
Probably the most surprising reason, but it has been scientifically proved that pain in the left armpit may be the consequence of some mental problems. Depression or anxiety often appear together with so called somatic symptoms, which include some unexplained pains in different parts of our body, sleeping difficulties, chronic tiredness and weakness, irritation, excessive sweating, or rapid heart rate.
Don’t try to fight depression or anxiety on your own as it’s usually a long and bumpy road. Go to a psychiatrist or psychologist who will know how to help you.
15. Other Causes
Some other, rare causes of pain in your left armpit include a bacterial infection, known as a glandular infection, which usually appears as a consequence of poor hygiene of your armpits.
If you have your shoulder dislocated, you can experience strong pain in the armpit too. The area may be also swollen or numb. Using crutches may also end up with pain in the armpits.
There is also a condition called hyperthyroidism, which may develop if you’ve been taking a lot of iodine. Your armpit may be painful and swollen then. Certain bacteria, known as mastitis and staphylococcus may cause some breast infections, which often result in pain in the armpit.
When to See a Doctor
Consult your doctor immediately if the pain in your left armpit is sudden and severe or when you also suffer from some other alarming symptoms such as chest palpitation, paralysis of any of your body parts, or breathing difficulties.
Also, you should make an appointment if you feel some suspicious lumps in your breasts area as it may suggest a condition in which only fast reaction guarantees full treatment. If you know what caused pain under your left armpit, for example a strained or overstretched muscle, simply wait a few days and if the pain doesn’t alleviate, then go to a doctor. Of course, in case of an injury give up doing sports for some time.
If it’s difficult to determine the cause of your pain, your doctor will have to run some extra tests and ask you some additional questions. Tell him when the pain started and if you experience other symptoms too. It’s possible that you will have blood tests done and that the doctor will examine your skin, ears, and throat.
