My mother is 52 years old. Normally she has a high BP using telma 20. The BP is controlled with that. Tablet. For the last 3 days she felt a headache and was very tired with small work. Her BP is 150/70 and Heart rate is 47. We went to a cardiologist and thyroid is normal, serum creatine normal and electrolytes normal. ECG is borderline ECG and the doctor said it is normal. Some urine and chest infection is there. Esr is 34. My mother is using 24 holters now. Now also She is having a heavy headache and is tired. Is it related to cardiologists or neurologists or in some studies it is showing as such a crushing effect. Please advice. Please don't tell me please consult online.
