I'm just a long-term patient: I have spleen deficiency and dampness, and now I have eczema and dermatitis.
According to my own experience of seeing a doctor and looking for information, generally speaking, we should ensure adequate sleep, proper exercise and a happy mood.
Besides, I think your wife may be cold, so keep warm.
Eat more foods that strengthen the spleen and stimulate appetite: yam, wax gourd, etc.
Besides, eat more hawthorn, appetizing, I have nothing to eat.
However, I sincerely advise you to find a good hospital and listen to the doctor. Don't disobey the doctor.
