Thank you for posting your query.
First of all, I would like to reassure you that the symptoms in your mother are not a cause of worry and we do not expect any serious illness.
It is possible that she has viral fever
or some other minor infection, casing fever. Headache could be a part of the febrile illness.
I would suggest that you give her paracetamol
for the relief of fever and headache. If she does not improve, you may take her to the doctor.
