Hello. Welcome to Healthcare Magic.
I would like to further your query. How old are you? Are on on any medication? Do you have any illness like diabetes/anaemia
or have you experienced a sudden increase in the number of infectious episodes over the past few weeks or months?
of sudden onset could signify an infectious cause , or a nutritional deficiency
state leading to decrease in immunity. Consult a physician for an evaluation; he would start a course of antibiotics.
