Abnormal bleeding in women is worrisome. This type of bleeding is not regular due to periods. Which means it is unrelated to menstrual bleeding.

Fever with a known cause is not a matter of concern. Usually, fever is due to bacterial, viral or allergic reactions.

Swollen Lymph Nodes

Fever indicates inflammation and infection in the body so are swollen lymph nodes. A general physician checks your lymph nodes to see whether they are swollen or do they indicate any infection.
