Hi, Welcome to Health care magic forum.
It appears that youhave some minor health problem, and it is not diagnised. It could be
anemia, or some chest problem like eosinophelia.
I advise you to consult a physician for diagnosis and treatment.you may have to go for tests like, Hb, D.C, E.S.R, A.E.C, besides other routine tests for diagnosis.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to improve the blood, and resistance against the infections.
Don't worry it is not a hypochondriac state.
Wishing for a quick and complete recovery.Thank you.
