Hello and welcome to HCM,
The symptoms of feeling dizziness
and appearing pale suggests that your son may have anemia
So, the first investigation to order is complete hemogram.
Cold sweats can be due to fever
. Check the temperature. You can visit your doctor for it or do it yourself.
The pulse rate and blood pressure can be monitored by your doctor.
A fasting blood glucose
level is within normal limits so the symptoms of dizziness are not due to hypoglycaemis.
So. it is best to visit your doctor for clinical examination and relevant investigations.
Thanks and take care.
