Hello
As you mentioned that you took treatment for
typhoid fever ( which was positive ) for 10 days .
After the treatment still fever present though low grade i.e. 99.4 degree, this is the cause of concern , that too in the after noon and in the evening.
So such type of symptoms may be due to these possibilities ,these include:
1
Tuberculosis , as the duration of fever is more than 15 days ,so get in chest X ray as well sputum for AFB and tuberculin pcr test.
2
Jaundice is another most common cause . Get in blood for hbasg for A B C E (
hepatitis 0
3 Dengue , because after initial stage in dengue causes
low grade fever. Get in blood for platelets count as well as serology test for dengue.
However , there are so many other reasons of such fever but physical , clinical as history of illness is important so consult another physician (2nd one ) and get his opinion.
Good luck.
