My daughter has had a bug bite on her arm for several days now. She has scratched it and picked at it, and yesterday she noticed a red streak swerving out from the bite. The bite itself is warm to the touch, red and swollen. What could the red streak be?
Hi, In my opinion, this is a bug bite which has now infected. If I was your treating doctor, I would have given an antibiotic like amoxyclav, Anti-allergic syrup like Atari, paracetamol for fever and mupirocin cream for local application. The dose of Chat Doctor.  I hope this has helped you. Regards
