Hello,
You may have had an insect bite, which became infected, or an allergic reaction, which progressed into infection. In either case you need to see a doctor and have some topical antibiotics prescribed to you. You should not linger, if the infection progresses into your scrotum, you may end up with a condition called orchitis, or epididymitis, both are very painful. It can also progress into abscess, which will lead to oral antibiotics and possible drainage. So, see a doctor, is my advice.
