Thanks for the query
and even heaviness in head may be due to anemia. Oral temp. 98.2 +/- 0.7 F is normal body temperature. Even there is diurnal variation and 0.9 F fluctuation can be seen. Body temp. usually towards higher side in late afternoon or evening is normal finding. Your backache
and pain in trapezius is is postural one. This temp has no relation with previous history of typhoid
So I would suggest you to go for Complete blood count
, do exercise, get a refraction
test for your eyes,and make a temp. chart to monitor the pattern of fever if any.
Wish you better health
