I haven't seen a doctor personally, and my level is limited. Personal views are for reference only.

Liu Xiaofeng, a doctor from Nanjing Maternal and Child Health Hospital, solemnly reminded me that I couldn't fully understand the illness because I couldn't see the patient in person. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
