Hi my father has a severe problem of aphthous ulcer. It first happened in 2016. The condition was so bad that we had to admit him to the hospital. After that he was fine. But in last 6 months it repeated two times. We were aware of the condition so he got the treatment early. But my question is why it is happening again and again? We visited a doctor at Bayrampasa but were not satisfied. Can you suggest a good doctor in Istanbul who handles this type of patient earlier?
