Patient: Mdm. Choo, 52 years old
Date: June 14, 2022. First consultation
Chief complaint: Back feels cold after a month recovery from COVID-19

Mdm. Choo was diagnosed with COVID-19 in May, and her symptoms at the time of diagnosis included a cough with less sputum, headache, and sweating. She took some oral medications to relieve her symptoms during the diagnosis, and the results came back negative about 7 days later. After a month of recovery, she experienced headache attacks, excessive sweating when she moved slightly, palpitations and a cold back, and felt lethargic after waking up in the morning, so she came to see us in the hopes of alleviating her discomfort through Traditional Chinese medicine treatment. I prescribed some Chinese medicines for warming Yang, reducing sweating and palpitations, and administered acupuncture treatment according to her symptoms, and I asked her to return for a follow-up consultation after taking the medicine.
Date: June 22, 2022. Second consultation
After a week, Mdm. Choo visited for a follow-up appointment. She disclosed that her palpitations and excessive sweating had significantly improved. However, she still occasionally experiences tightness and discomfort in her head and still feels cold in her back. I still administer acupuncture to her and modified her Chinese medicine after combining her tongue and pulse diagnoses.
Date: June 29,2022. Third consultation
Mdm. Choo returned and provided feedback, revealing that her sweating problems occur obviously at specific timing after taking the herbs and changes according to her daily routines so there is no way to tell a specific attack time. She also revealed that the headache problem has been resolved, unlike the previous will occur from time to time, and that she felt her health was improving overall, with the exception of the back, which is still frequently feeling cold.
Date: July 20, 2022.Forth consultation
Mdm. Choo went back for a follow-up appointment a month later. She revealed that her health had significantly improved, as had the sweating, headache, and problem with chills behind her back that she had previously experienced. She rarely felt uncomfortable at the moment, and occasionally, after working out, she would feel cold in her back, but the other issues had largely subsided. I then modified the Chinese medicine and gave her an acupuncture treatment while informing her that she did not need to schedule a follow-up appointment if she felt fine after taking the medication.
【Pathological analysis】
Mdm. Choo took numerous oral medications to relieve her symptoms during her COVID-19 infection, including antipyretic medicines with cold properties. Taking a lot of cold medicines damages the body’s Yang Qi, and a lack of Yang Qi can’t normally warm the body and inability to keep fluid causing a chill on the back and excessive sweating. Yang deficiency damages the heart and induces palpitations.
【How to nourish yang qi】
Yang Qi is the most fundamental substance for sustaining human life activities and the basis of the body’s life. You must make sure that Yang Qi is abundant and smooth if you want to keep your body healthy and stop diseases from developing. The abundance and smooth flow of Yang Qi is the key factor in determining whether or not the disease will occur.
- 1. Adequate sun exposure.

According to TCM, the back represents Yang, while the abdomen represents Yin. The Yang meridian travels more on the back while Yin meridian travels more on the chest and abdomen. Going outside to sunbathe between 7-9 a.m., when the sun is not too hot, can charge our bodies’ yang meridians, replenish the yang qi, and also open the pores of the body, allowing harmful substances accumulated in the body to be discharged by slightly sweating.
- 2. A regular routine

A healthy lifestyle is the most effective way to nourish Yang Qi and extend life. Adopting a healthy diet, balancing work and leisure, and maintaining a calm state of mind can all help to ensure that the body’s yang qi is sufficient and smooth. It is not difficult to prevent diseases as long as you follow nature’s laws.
- 3. Exercise

Moving nourishes Yang, while resting nourishes Yin. Proper exercise is required to maintain the smoothness of Yang. Exercise according to body strength to achieve the goal of nourishing Yang Qi, as excessive exercise will not help to regulate the Qi and blood in the body, but will instead harm the Yang due to overexertion. If the elderly does not want to exercise vigorously, they can practise tai chi and qigong such as Ba Duan Jin (Eight-section brocade) in the morning.
