Reply to the question 1:
My nose often itches for no reason.
Consideration is a kind of rhinitis: mild allergic rhinitis.
Answer to question 2:
My arm itches when exposed to the sun, and there is a little thing on it, which is similar to chicken skin, but it is not. Even if the sun doesn't shine, it tickles as long as you scratch it, and then you can't scratch it.
1. This is the symptom of solar dermatitis and allergy caused by long-term exposure to ultraviolet rays after the body's resistance in all aspects has decreased.
If it is sporadic, it will take a few days and the allergic symptoms will recover on their own. If you are allergic for a long time, it is recommended to go to the hospital for dermatological treatment in time.
2. If the body is allergic, first find the allergen, find out what causes your allergy, and then do targeted treatment. Don't touch these allergens in your daily life, and pay more attention to prevention in this respect. This is the key to curing physical allergies. The skin has been allergic or uncomfortable because of its sensitivity. Be sure to find out what the allergen is.
3. Pay attention to sun protection, eat more fruits and supplement vitamin C to the skin. It's best not to eat spicy food, fish, hair and any irritating food during this time. Do a good job of sun protection to prevent pigmentation. Also, don't scratch. There are bacteria under your nails that will infect you. Wash your face in cold water and go to see a doctor quickly. Don't delay.
4. Don't put ointment on yourself! If you don't clean it well, it will be more serious.
5. It is recommended to find Chinese medicine for conditioning.
Go to the hospital for allergen skin prick test. This skin prick test is to drop a small amount of high-purity allergen liquid on the patient's forearm, and then use a needle to penetrate the skin surface.
If you are allergic to this allergen, within 15 minutes, a red lump similar to a mosquito bite will appear at the bitten part, resulting in itching reaction or color change.
The existence of allergic diseases can be basically determined, which is mainly used to detect immediate allergic reactions.
Judge what causes your skin allergy, so as to pay more attention to this problem in the future.
I also suggest you take a patient look at this.
