<s>[INST] I broke out in a rash today on my stomach and thighs...I heard drinking red bull can cause this (as I drink 3-4 per day) I also heard stress can cause this (as I have an interview later this week) and I also heard insect bites can cause this (as I was knocking down cobwebs earlier today) Which of these are most likely??? [/INST] Hi, You seem to have developed an urticarial rash. It seems to be most likely due to insect bites followed by a red bull drink. Take antihistaminic like tablet Cetirizine. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Asmeet Kaur Sawhney, Dermatologist </s>
