<s>[INST] I have been bitten by some bug, I think in overgrown grass. It looks like a mosquito bite in size but has a large ring/rash around it and itches like crazy. Very slightly warm to the touch. Any idea what this might be and how can I stop it from itching and spreading? [/INST] Hi, I have gone through your complaints and it is very difficult to comment on the nature of the insect bite. I would recommend you to take antihistaminic like tablet Cetrizine twice daily and apply topical steroid like Cortisone cream on the affected area twice daily for few days. This will resolve the reaction. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Asmeet Kaur Sawhney </s>
