Before consulting a doctor, you can observe and record some relevant information yourself, such as time, place, frequency, factors that aggravate or alleviate the disease, etc. This will help doctors better understand your situation and provide more accurate diagnosis and treatment suggestions.
Maintaining good hygiene habits in peacetime is also an important measure to prevent and alleviate skin problems. Keeping the skin clean and dry, avoiding excessive friction and irritation, and choosing skin care products suitable for your skin can all play a role.
Be sure to consult a professional doctor when determining whether it is dermatitis or not and choosing a treatment method. They will work out the most suitable treatment plan for you according to your specific situation. I hope you can get effective treatment as soon as possible and get back to health!
