Welcome to HCM.
You had a needle stuck 6 months back and tested negative for HIV. So forget about that.
The second needle stuck is after a shot to a 3 year old boy. A 3 year old boy having HIV or Hepatitis
is quite uncommon. The earliest manifestations of HIV can occur only after 4 weeks only. Hepatitis would not be manifest with sore throat
and swollen lymph nodes
. So your symptoms might be due to an ordinary throat infection
that any body can have possibly through Strepto-cocci.
If you meet your physician he will be able to cure you.
Regarding HIV test
you need not wait up to 6 months. The results are highly reliable and conclusive after 12 weeks. If you are so anxious, there are HIV tests available in certain big laboratories which are reliable and more conclusive after 3-4 weeks of the needle exposure.
Nothing to worry.
