• This looks like urticaria (hives), most likely cholinergic urticaria triggered by heat, sweating, exercise (gym), or body temperature rise
• It is due to histamine release in skin, not an infection
• Lesions appearing and disappearing quickly supports this diagnosis
Helpful Tips / Words of Caution:
• Avoid triggers: excess heat, tight clothes, hot showers, sudden temperature changes
• Wear loose cotton clothes during workouts
• Keep skin cool; take cool showers post exercise
• Do not scratch → can worsen hives
• Usually harmless but if lip swelling, breathing difficulty → need emergency care
