Thank you for your query.
I would have appreciated if you had mentioned the values of iron, calcium and white blood cells for me to give you a better guidance for your cousin. If indeed her haemoglobin
is less with low iron and low calcium then supplementation should give your cousin relief in the pain and also on the scab that you describe.
You mentioned that your cousin has glandular fever
which is not getting better. A description and investigation findings would have been better. If glands are swollen then has a biopsy
been performed on them. If not then discuss with your doctor who shall guide you accordingly.
I hope I have answered your query to your satisfaction.
Wishing your cousin all the best.
