Hello,
Thanx for the query, I am hoping to advice the best possible to you.
It will be wrong if I say that your ulcers are surely due to the Aldara cream you are using but possibility of this can't be ignored. Your ulcers may be due to nutritional deficiency or due to any other medicines or may be due to stress.

I am advising few things to relief the symptom

• Avoid hot and spicy food and beverages for few days.

• Maintain a healthy lifestyle to help manage stress — eat a healthy diet,
exercise regularly and get enough sleep. Having a healthy lifestyle will
help you manage periods of high stress

• Eat more green leafy vegetables and have diet rich in protein.

• Rinse your mouth with Betadene/Viodine/Betakind gargle (contains
povidone iodine solution) easily available in medical stores, twice daily.

• Apply mucopain/dologel to the affected area 3-4 times daily.

• Take antioxidant+multivitamin capsule once daily for 15 days.

• You may discontinue Aldara cream for few days precautionary. But do
consult your doctor before discontinuing.

Hope this will help you. If there is any more query or question regarding this in your mind, you are free to ask any time.

Take Good Care of yourself

Regards

Thanks for using health care magic.

Read your query.

I advice you to apply Mucopain gel on the lesion two to three times a day.

Take multivitamin tablets for a month.For the pain you can take paracetamol.

If still persisting consult your dentist.

Thanks and regards.
