It may be simple inflammation of nerve endings (pseudorheumatism) caused by excessive fatigue of nerve endings.

Cause of disease: 1, long-term exposure to bad living and working environment such as damp heat or cold; 2. Nerve endings fatigue caused by labor transition; 3. Excessive blowing of fans and air conditioners for a long time causes excessive fatigue of nerve endings;

Coping methods: improve the living environment in time, avoid bad living habits, rest and adjust; Use musk, massage and other drugs to promote local blood circulation-when all the peripheral waste is excreted, the symptoms of rheumatism can be alleviated, the symptoms disappear and there is no recurrence.

If the symptoms disappear when the body temperature is high, then your mother is probably a congenital physical deficiency as mentioned by Chinese medicine, and there was nothing when she was young. When she is old, she may have yin-yang imbalance, showing yin deficiency in spring and summer and yang deficiency in autumn and winter.
