Like copper coins, red circles are mostly caused by pressure and mosquito bites, and may also be due to nummular eczema, ringworm, pityriasis rosea, etc. It is necessary to go to the hospital for examination in a timely manner to clarify the cause before treatment.
1. Pressure: If the local skin is accidentally pressed by a round hard object, it may lead to the rupture of local capillaries, causing the above symptoms. This is a normal physiological phenomenon and generally requires no special treatment, but attention should be paid to local hygiene.
2. Mosquito bites: If bitten by a mosquito accidentally, its saliva may remain on the skin, causing small bumps, redness, and swelling. It can be improved by applying floral water locally or using a cold towel for cold compresses, which can help vasoconstriction and alleviate the symptoms.
3. Nummular eczema: This disease may be caused by familial inheritance, excessive mental stress, etc., often leading to round plaques, severe itching, and other symptoms. Avoid scratching the affected area arbitrarily to prevent worsening of the condition. Drugs such as hydrocortisone butyrate cream, mometasone furoate cream, and betamethasone propionate cream can also be used as recommended by doctors to have anti-inflammatory and anti-allergic effects.
4. Tinea corporis: It is more likely caused by fungal infection on the skin surface, which may cause round or crescent-shaped red rashes, moss-like changes, and other symptoms. It can be regulated by cryotherapy to help inhibit the growth and reproduction of fungi. Drugs such as clotrimazole ointment, miconazole nitrate ointment, and itraconazole capsules can also be used under the guidance of doctors to help kill fungi.
5. Pityriasis rosea: It may be caused by viral infections, immune dysfunction, etc., easily causing skin inflammatory reactions and leading to rose-shaped oval plaques, rashes, and other symptoms. It can be improved by medium-wave ultraviolet phototherapy, which helps promote the subsidence of skin lesions. Drugs such as loratadine tablets, compound dexamethasone acetate ointment, and halometasone ointment can also be used as adjuvant therapy under the guidance of doctors to help alleviate disease reactions.
In daily life, always pay attention to the development of the disease, regularly go to the hospital for follow-up visits, and also pay attention to maintaining regular habits, ensuring sufficient sleep, and avoiding staying up late for a long time.
