From your situation, you can know that your grandmother should be treated by Chinese medicine. There is a Chengde Chinese Medicine Hospital in Chengde, which is mainly based on Chinese medicine. You can go there for consultation. There are many old Chinese medicine practitioners who have been practicing medicine for many years.
There are also good hospitals in Chengde, the first is the Affiliated Hospital of Chengde, the second is the Central Hospital of Chengde (this is not a Chinese medicine hospital), and there is the 266 Hospital.
But let's go to Chengde Chinese Medicine Hospital first.
I hope your grandmother will recover soon (* _ _ *) ~ ~ ~
