Mouth ulcers.

Assalamualaikum wa rahmatullahi wa barkatahu to all my brothers and sisters.
From a few days i have mouth ulcers which have spread whole of my mouth.(5 days). And it's really hard to eat or drink anything, i even consulted a doctor, and got few medicines prescribed, I even followed the home remedies. But nothing is of use, I'm not able to talk properly now, and it hurts really bad , Is there any islamic cure for this?

Time and time I have used Bonjela which has proved to be effective ON CONDITION one rubs it in the ulcer (ouch) to make it stay secondly repeat it every 2 hours because the medicine got swallowed. Don't expect immediate miracle. Follow my advise and only on the third day onwards (especially the big ulcers) will you see positive results. Best of luck.
