The feeling of a cold throat until the back of my head and a shivering sensation is what s going on

Hello, your current symptoms are considered to be a manifestation of pharyngitis.

The general recommendation is to consider oral drugs such as roxithromycin (if severe cough, increased sputum, sore throat, etc.) during a sudden attack**, and can contain such as Yinhuang containing tablets, golden throat treasure, etc., and can also be used to make tea with Chinese herbs such as fat sea and honeysuckle.

It's better to see a doctor in time. It would be better to be in time.

Air conditioning does not refrigerate is not fluoride can solve the problem, air conditioning does not refrigerate, in addition to the lack of refrigerant, there are five reasons:

1. The power supply voltage is not enough. The normal starting voltage of the air conditioner is 220V+-10%. In China's power supply system with a phase voltage of 220V and a line voltage of 380V, almost all compressors above 200V can be started.

At 180V or more, 70-80% can be started, and at 160V or more, only a few can be started. I've done it myself. Below 160V there is almost no possibility of starting.

As a rule of thumb, the compressor starting voltage is more reliable above 190V.

2. The power of the air conditioner is not enough. The general selection principle is: 150-250W square meters for cooling and 250-350W square meters for heating, in addition to comprehensive consideration of factors such as space height, level orientation, sealing performance and residential population.

3. The outside environment temperature is too high. There is a common saying: when the outdoor unit is in an environment above 43°, most air conditioners are difficult to transfer the heat from the indoor to the outside, resulting in no refrigeration.

4. The air conditioner is not cleaned and maintained for a long time. If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. Because the outdoor unit is exposed to the outdoors, it is easy to absorb dust and debris, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the reduction of the cooling effect of the air conditioner.

The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria and pollute the air.

5. The copper pipe connecting the indoor unit and the outdoor unit is too long. The maximum allowable length of the connecting pipe of the air conditioner shall not exceed 8 meters for a horse, 10 meters for a horse, and 15 meters for more than 2 horses. The height difference between indoor and outdoor units shall not exceed 5 meters.

If you add it to it, if it has not been leaked, it may be added to leak quickly, and it is not necessarily a lack of fluorine, and many reasons such as the external machine not working may cause not to be cold, please check it for professional repair.

Swallowing saliva is also useful when you feel that your throat is dry and cold. It's all winter performance.

Cold throat is persistent -- presumably associated with cholecystitis and gastritis attacks.

When these two types of inflammation occur together, it is easy to cause stomach acid to reflux into the middle and upper esophagus and cause laryngeal discomfort. This is one of the common phenomena in medicine.

It is recommended that you go to the hospital for a check-up** to see if the doctor is addressing the problem from the side of reflux esophagitis.

I got cold. Because the head is in the upper part and the wind is light, it is most likely to invade the upper part of the human body. Therefore, when it is windy, especially in winter, the head is susceptible to wind.

Keeping warm, wearing hats and scarves is the easiest way to prevent wind evil and maintain health. Also, when sleeping at night, the head and neck area must not be facing the air outlet. Drink some hot water and massage it after the wind can relieve it.

Dear, take care to protect your body.

The cold air inhaled outside is too much.

After taking Chinese medicine, the doctor will prescribe medicine to you according to your condition, and slowly adjust the functions of the human body back to be ok.

Daxi tablets can quickly relieve symptoms.

You can guess that the quick difference can be a cold and indigestion, you can use Sanjiu Cold Ling**, indigestion can be used, Baohe Changyin Pill Multi-enzyme Tablets**, usually don't eat food that is difficult to digest, it will get better slowly.
