<s>[INST] I am a female 86 years old. I have had sores in my mouth and gums for several months. I have been to 7 doctors and none of them can cure me. They have given me oral mouth wash solutions, none have helped. one physician said they my condition is common with females my age. [/INST] Hi, Welcome to Chat Doctor .com. I had gone through your question I can understand your concern about your sore mouth. As per your history you only had a complaint of sore mouth. If it is only painful and no other lesion associated you can use analgesics gel (DICLOFENAC gel). If you have red or white patches on it, it may be candidiasis (fungal infection). Or it can be any of the autoimmune disease too. You can upload some picture or email me at Chat Doctor. Com, so that I can guide you better. Hope my answer will help you and visit us back if you have any questions further. Regards  </s>
