There are big red spots on the armpits

Large red spots on the armpits may be caused by eczema or tinea versicolor, or skin diseases such as folliculitis, which will cause red spots and itchy skin.

1. Eczema: Eczema is a relatively common skin disease. It may be caused by genetics or dietary influences. For example, eating seafood and other foods that are prone to allergies will cause large papules to appear on the skin, and may also cause problems such as skin itching. You can apply calamine lotion locally to relieve itching symptoms. In severe cases, you can also take loratadine orally.

2. Tinea versicolor: Tinea versicolor is caused by infectious factors, such as Malassezia infection. If you sweat a lot in the armpits, it may increase the chance of infection, causing local red spots and causing skin itching. Antifungal drugs can be used for treatment, such as ketoconazole cream or clotrimazole cream, and itraconazole can also be taken orally;

3. Folliculitis: Folliculitis is usually caused by bacterial infection, such as Staphylococcus aureus, which will cause skin redness, swelling or itching. Antibiotic ointments are needed for treatment, such as erythromycin ointment and mupirocin ointment, which can reduce inflammation as soon as possible and relieve symptoms.
