A middle-aged man in his early 50s suddenly developed cold-like symptoms accompanied by headache, nausea, and vomiting. Attributing his discomfort to fatigue and irregular eating habits, he assumed rest would lead to recovery.
Several days later, however, his vision began to deteriorate. By the time he sought medical care, he had already lost more than half of his vision, and the optimal window for treatment had passed, said Jonathan Liu, a traditional Chinese medicine practitioner and contributor to The Epoch Times. The man was diagnosed with acute angle-closure glaucoma, a condition that can show up as a sudden headache and nausea.
