The money received from the VA Funding Fee is used to offset the few loans that go into default, and further reduces the cost to taxpayers, ensuring the VA Home Loan program continues for future generations.
Not likely. Most swollen or inflamed lymph nodes in the groin are not due to STDs, and gonorrhea and chlamydia don't do this. (There is a special kind of chlamydia called lymphogranuloma venereum or LGV, which causes this kind of problem, but extremely rare and almost never in heterosexuals.) If you're at risk for STDs, get checked for gonorrhea or chlamydia -- but not because of lymph nodes in the groin.
Lymph nodes become swollen in response to illness, infection, or stress. Swollen lymph nodes are one sign that your lymphatic system is working to rid your body of the responsible agents. More serious conditions, such as immune system disorders or cancers, can cause the lymph nodes throughout the body to swell. Immune system disorders that cause the lymph nodes to swell include lupus and rheumatoid arthritis. Any cancers that spread in the body can cause the lymph nodes to swell. When cancer from one area spreads to the lymph nodes, the survival rate decreases. Lymphoma, which is a cancer of the lymphatic system, also causes the lymph nodes to swell. Some medications and allergic reactions to medications can cause the lymph nodes to swell. Anti-seizure and antimalarial drugs can also cause lymph nodes to swell.
