What is the reason for different parts of the body to take turns bulging?

What's the reason that the chin is stiff and painful to press?

The long and hard puff of the chin is very painful to press, and this situation is considered to be an inflammation and infection of the local tissues, and if left unchecked, a small pustule of purulent pus often appears. It is an acute purulent inflammation of the local hair follicle or sebaceous gland. In the early stage, local warm compresses, such as magnesium sulfate with a concentration of about 30%, or alcohol with a concentration of 75%, can help promote the resolution of inflammation, and antibiotics can be given under the guidance of a doctor**, such as oral amoxicillin capsules or cephalosporin antibiotics.

What's the deal with the long bag on the head?

Long bag on the head, the most common ** is sebaceous cyst, also known as powder tumor, which is generally round, or oval, you can look at the surgeon, through surface touch, you can basically determine the diagnosis, and then give the corresponding ** measures. Because it grows in the scalp and is covered by hair, it does not affect the appearance, so if it is determined to be a sebaceous cyst, it can also be ignored and continue to observe. Or if the volume of the sebaceous cyst is relatively large, a minor operation can be done after local anesthesia, which can be completely **.

The bulge is formed due to: the internal carcass cord breaks, the binding force decreases, and the internal gas of the tire jacks up the rubber from the cord break.

Hello! Due to the high speed of the car, the tire shoulder or the sidewall close to the shoulder of the tire strongly impact the external foreign body (such as potholes, curbs, large stones), resulting in serious extrusion between the tire rim and the external foreign body, the carcass cord is overstretched and causes breakage, and the air inside the tire is jacked up from the broken line to form the sidewall bulge.

Suggestion: If you have to drive in poor road conditions (e.g. potholes, curbs, large rocks) when the tires are cooled, please increase the air pressure of your tires appropriately on the basis of the air pressure parameters provided by the car manufacturer under normal load conditions, but remember not to exceed the air pressure parameters under the maximum load condition specified by the car manufacturer. When driving in poor road conditions, please pay attention to avoid potholes and other external foreign objects, and if you cannot avoid them, please reduce your speed, because the harm caused by high-speed collisions is much greater than that at low speeds.

Hello, the tire bulge is caused by the aging of the tire and serious wear and tear, and it needs to be replaced in time.

Tire bulging is mostly caused by the side cord breaking due to the sidewall being squeezed by a hard object. The edge of the pit can easily squeeze the tire cord off when passing at high speeds, causing bulging. Finally, there is the quality of the tire itself, in which case the tire manufacturer or seller will replace the user with a new tire.

Cracks, stickiness, hardening, softening, chalking, discoloration, and mildew are a manifestation of the aging of all rubber products, and automobile tires are no exception. So to what extent do tires need to be replaced?

First of all, starting from the material of the tire, the main body of the tire is rubber, and the longest storage and anti-aging time of rubber from natural latex to ethylene propylene and nitrile will not exceed 10 years, and the average service life of various rubber products in use is 3-5 years.

Tires carrying the weight of the vehicle are often responsible for slowing down the cushioning effect, and they also have to resist corrosive rain and cleaning fluids from car washes. Therefore, the aging of tires will be greatly reduced.

Generally speaking, the life of tire wear is 3-50,000 kilometers, if the tire has not reached the wear limit and mileage, but the service life of the tire reaches 5 years or a large number of cracks on the side, it is necessary to replace the tire.

Why do car tires bulge? What causes it?

The expiration date has passed.

Tires that have been used for many years have passed their shelf life, and tires are aging and will bulge when they hit stones or speed bumps during driving.

Improper use. In fact, the bulge of most tires is caused by improper use, generally the tire has suffered a large impact, such as passing the speed bump without slowing down, there are pits and stones in front of you that you don't see, and you don't slow down. If the speed is fast, it only takes one impact on the tire to bulge.

Low tire pressure.

Because the tire pressure is too large during the use of the tire, the tire landing area is reduced, the tire is worn early, and the tread temperature rises due to rolling acceleration or tire heat dissipation during the use of the tire.

Tire quality problems.

There is a quality problem with the tire, the cord is unevenly distributed, and the cord strength is insufficient, which can also lead to bulging.

Hello, considering urticaria, terfenadine and cetirizine ** can be selected according to the condition and clinical manifestations. In severe cases, steroids such as prednisone tablets can be used**, and calamine lotion or zinc oxide lotion and parisone cream can be used for severe local itching or rash, which can achieve temporary efficacy, and should follow the guidance of the clinician, and wish good health.
