My husband is suddenly had a boil in left upper lip from yesterday and in the night it got popped up . And it's extremely painful, his total left side cheek bones got swallen, he can't even open his mouth properly, inside left cheek bones also swellen. Whenever he is eating its getting pain and little bit of burning sensation. Today he took azithromycin 500 once. For  pain relief he took calpol 650 yesterday and today. Could you please suggest any other  medicine or remedies. I am attaching the photos. TIA
