What to do if you get rashes on your body due to cold

If you get some small bumps on your body when you catch a cold, in most cases it is urticaria, a common symptom caused by skin allergies. It may mainly be caused by an allergic reaction. Generally, people with allergic constitution will develop urticaria after eating fish, shrimp, eggs, beef, etc. Therefore, you must pay attention to your diet and actively look for allergens.

Skin allergy is an abnormal reaction of the skin to external stimuli. When the allergen contacts the body, it prompts the body to produce corresponding antibodies, triggering an antigen-antibody reaction with varying degrees of severity. Common manifestations include redness, itching, red blood streaks, dryness and desquamation, blisters, small red bumps, tingling, burning and tightness.
