I have got some kind of wound inside my mouth cheeck from last 3-4 days which seems small bulge with might be pus like swelling (light white colour) and cut with small dots marks. It pains a lot and causing discomfort while eating and opening mouth. Picture attached with wound mentioned to locate the area. Also my gums has swollen and seems like coming over last few teeth. Can you suggest what could be reason and how I can get some relief from it. I have taken becosules tab from yesterday evening but not much improvement. Since my city has lockdown till month end can't visit any dentist as well as they are not seeing in opd.
