In our daily life, we may encounter this situation: small red rashes or bumps will appear on our skin somehow, what is going on? What should we do about it? First of all, you should seek medical advice and treatment from a regular doctor in a regular hospital; if you cannot seek medical advice in time, you can observe it for 1-2 weeks, do not use any medication on your own, and do not wash it with hot water or soapy water or other irritating liquids, and do not scratch, tear or pick it out, knowing that our skin sometimes has small transient problems due to diet, climate or emotions, and these problems sometimes diminish over time and even heal themselves. If you are subjected to medication or mechanical stimulation, you will instead aggravate these small problems and develop into serious skin diseases. Second, if, after observation, the skin abnormality does not improve, but gets worse, you should consult a doctor as soon as possible and actively treat it, while avoiding all factors that may aggravate the skin disease, such as smoking, alcohol, spicy, staying up late, excessive sun exposure, etc.
