hello, i just got hit by a ball on my face (mouth technically), and hence i developed 4 ulcers on my gum, 4 ulcers on upper lip and 3 ulcers on lower lip, its painful to even drink water and speak, my friend told me to apply powder from becosule capsule directly on the ulcers. he said it would pain at first then heal immediately, is the solution appropriate or any other advice
