Many people will have small pimples on their back in summer. If they touch it with their hands, they will feel uneven. They can scratch gently and even scratch some small grease particles.

What are the small bumps on your back

1、acne
Acne is a chronic inflammatory skin disease of hair follicle sebaceous gland unit, which can be divided into pimples like white head, blackhead acne, inflammatory papules, pustules, etc. according to the severity. In hot weather, it is easy to sweat, and the sebaceous gland will also secrete more oil. If too much oil and dead skin accumulate and block the pores, it is easy to bulge small pimples, namely white head and black head acne. Once the acne is infected by bacteria, it will become inflamed, red and swollen, and become a "pustule". If the pustule continues to deteriorate, it will escalate into large and small dark red blocks, which are also called "nodules". If there is more pus in the card, it is called "cyst". If it is left alone, the cyst will even become larger and larger, and even grow to nearly 10cm. This is not a matter of painting medicine, and it must be removed by surgery.


2、Folliculitis
Folliculitis is mainly caused by bacterial or fungal infection, one is bacterial folliculitis, the other is fungal folliculitis.
Bacterial folliculitis: looks like millet, with white purulent head. It is generally caused by excessive sweating and incomplete cleaning. For example, I didn't take a good bath and rub my back, and I didn't wash and change the sheets frequently.
During the day, my back is wet, hot and dirty in my clothes, and when I sleep at night, I will be rubbed by dirty sheets. If I accidentally get infected with "Staphylococcus aureus", I will get "bacterial folliculitis".
This type of small pimple on the back is hard to be cured by laissez faire. You have to go to the hospital to prescribe medicine, and it will take 1-2 weeks at the earliest to disappear.
Fungal folliculitis: It is redder, rounder and larger than bacterial folliculitis.
If you don't pay attention to hygiene in summer, you may also be infected with "Malassezia", causing "fungal folliculitis". This Malassezia, originally living in human hair follicles, looks very honest at ordinary times. When encountering a high temperature, high humidity and high oil environment, it starts to breed crazily and start doing things.
Data shows that 75% of Malassezia folliculitis occurs in summer, more men than women, and it is more painful than bacterial folliculitis, painful and itchy, and takes longer to treat, about 1 month.

3、Papular urticaria
Papular urticaria, round or spindle shaped, a little hard, red patch. This kind of pimple has no characteristics, but it has one of the biggest characteristics: itching.
A scratch may also swell up and become a piece. It is papular urticaria, also known as "summer mat dermatitis". You can see from the name that it came out of the mat. Maybe the mat was not cleaned, or it was bitten by mites hidden on the mat. If you are bitten, you will see a needle size bite mark on the pimple. In this case, the doctor will let you take anti allergic drugs.
Warm reminder: these small pimples cannot be picked!
These small pimples, the more serious they are, the worse the whole back will be, and they may also be "scar pimples"!

How to prevent acne on the back

1、Change clothes frequently
The weather is hot, especially for those with a sweaty constitution, who often sweat like rain.
If you sweat and get your clothes wet, do not bear it. Change dry clothes in time and do not provide conditions for the breeding of mites and bacteria.

2、Pay attention to back cleaning
When some people take a bath, because they can't reach their back, they ignore it directly and wash other parts, which is easy to cause acne on their back.
It is worth noting that the back should be cleaned in time to remove excessive oil secretion and pay attention to skin hygiene.

3、Timely change the sheets
Try to wash once a week and dry in the sun. The mat is made of bamboo and rattan, so it is not easy to be allergic. It is better to "scrub it every day and air it every Monday".

4、Daily taboos
The occurrence of acne is closely related to the level of sebaceous gland secretion, which is related to diet. Acne patients should avoid taking too much dairy products daily; In addition, foods high in oil, sugar and GI (glycemic index) will aggravate the secretion of sebum, which is a dietary blacklist for acne patients.
To sum up, even if you have acne on your back, don't panic. First, pay attention to cleaning and taboo, and then cooperate with symptomatic medicine, but more importantly, do a good job in daily prevention!
