Hello,
Your mother's symptoms of dizziness, nausea, sweating, weakness, and persistent dry cough following a viral-like illness require further evaluation, particularly at 66 years of age.
Possible causes include:
Post-viral fatigue: Weakness and reduced exercise tolerance may persist after respiratory infections.
Dehydration or orthostatic hypotension: These can cause dizziness, thirst, nausea, and weakness.
Respiratory infection: Persistent cough with an elevated
CRP may suggest ongoing inflammation or infection.
Cardiac causes: Sweating and weakness during walking can occasionally indicate cardiac ischaemia, even without typical chest pain.
Her CRP of 22 mg/L indicates inflammation but does not establish whether the cause is viral or bacterial.
Although the normal ECG and troponin are reassuring, they do not completely exclude all cardiac problems, especially when exertional symptoms continue.
Next Steps
Arrange a medical reassessment today, preferably with a general physician or internal medicine specialist, because she continues to experience weakness and sweating during walking. Check blood pressure (lying and standing), pulse, oxygen saturation, temperature, and blood glucose. Consider chest X-ray if the persistent cough has not already been investigated, particularly given her age and elevated
CRP. Depending on clinical examination, investigations may include
electrolytes,
kidney function, glucose/
HbA1c, and repeat CRP if clinically indicated. Because she experiences sweating and weakness with exertion, her physician should reassess whether further cardiac evaluation is required. If dizziness persists, a neurological and vestibular examination may help identify balance-related causes.
Health Tips
Encourage adequate hydration, regular meals, and rest. Avoid prolonged walks or strenuous activity until her symptoms have been assessed. Do not start antibiotics solely because
CRP is elevated. Treatment should depend on clinical findings and evidence of bacterial infection. Seek medical attention if she experiences chest discomfort, breathlessness, fainting, confusion, severe dizziness, cold sweating, or sudden weakness. My recommendation: A post-viral illness is possible, but her age and recurrent sweating and weakness during physical activity make it important to exclude cardiac and respiratory causes before attributing everything to viral recovery. Her normal initial investigations are reassuring, but persistent symptoms warrant reassessment. Wishing your mother a speedy recovery!
