Hello Welcome in H.C.M. I have gone through your query regarding throat pain developed after spray of anti mosquito repellent 7 days back, though you have taken antibiotic and done warm saline gargling. Here I would like to tell you that you had developed allergic inflammation in throat. Though in initial stage use of steroid gives excillent results but now 7 days are already passed so you may take now- 1- Fexofenadine (120 mg) daily for 7 days. 2- Mucolytic. 3- Warm saline gargling. I hope above treatment will help you. One thing is very important that if you are a diabetic fellow that simultaneously your blood sugar should be maintained. Regards.
