Hi there ..
This needs to be seen in person if possible and as you appear to be in namm Bengaluru, welcome to come across.
Alternatively, do consider an INSTANT ONLINE Consultation on this App🙏
The correct antibiotic needs to be taken and for that, you will do well to go to a lab 🧪🧫 and get the pus tested for Antibiotic sensitivity to see which will suit you the best depending on the MIC values on the report. Connect having done this test.
Don't worry it can be sorted.
Health Tips
In the interim, Brufen 400 twice daily post meals will help with the swelling (assuming you don't have any renal issues or
diabetes that are contraindications to NSAID use); best to get a prescription.
