Traditional Chinese Medicine Doctor

This afternoon I took a half-day off and went to see a Ttraditional Chinese Ddoctor named Dr. Chao for my feeoot pain.

Even her mother's diabetes that had lasted for really a long time, after Doctor Chao's one month treatment it was brought under control was brought under control after one month of Doctor Chao's treatment.

Sorry, I forgot to delete “it” after “treatment.” I’ve fixed that now.

My feet have been aching on-and-off aching since half a year ago.

Hope it works this time.

This is OK in a casual context, but to be grammatically correct, you need to add the subject, I: “I hope it works this time.”

This afternoon I took a half- a day off and went to see a Ttraditional Chinese Ddoctor named Dr. Chao for my feet pain.

I heard about the doctor from my wife's bestie friend.

"Bestie" is more informal, though it is right depending on the level of formality you were intending here.

She mentioned that Dr. Chao was very professional and Ddoctor Chao's treatments worked like a charm.

Even her mother's diabetes which had lasted for really a long time, after Done month of doctor Chao's one month treatment, it was brought under control.

My feet have been aching on-and-off aching since half a year agofor the past six months.

I saw(/went to see) Western doctors twice but they didn't help.

HI hope it works this time.

In a casual context, bestie works here. In a neutral context or a more formal context, use best friend.

Since I can't determine Dr. Chao's gender, I used their as a gender neutral pronoun.

Even her mother's diabetes had lasted for really a long time, after Doctor Chao's prior to coming to Dr. Chao. After their one -month treatment, it was brought under control.

My feet have been aching on-and-off aching since a half a year ago.

I saw Western doctors twice, but they didn't help.

So I decided to try a TCM doctortraditional Chinese medicine this time around.

*even if it is both feet, you would say 'foot pain'

She mentioned that Dr. Chao was very professional, and Doctor Chao's treatments worked like a charm.

Even her mother's diabetes that had lasted for really a long time, after Doctor Chao's one month treatment it was brought under control.

You might want to rearrange this one for clarity.
After just one month of treatment with Dr. Chao, her mother's long-time diabetes was brought under control.

My feet have been aching on-and-off aching since half a year ago.

*or
My feet have been aching on and off for half a year now.
