Hi,
Noted your history of recurrent cancer sores, pain in throat and ear pains.
The commonest causes I can think about are as follows:
Reduced immunity causing all the three problems thus
herpes simplex appearing as cancer.
Recurrent
throat infection is due to exposure to community and thus you have to identify the people and area to keep away from.
sores in mouth and tongue can be due to
aphthous ulcers and usually related to stress,
anxiety, colitis, IBS and so on.
Detailed clinical evaluation, investigations and proper management can help you to come out of this.
Do
Povidone Iodine gargles 2 times a day.
Sips of water orally frequently as these help for the self cleaning of mouth.
Further complete management as per the causes found.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
