You have been told MANY times before that you initial sexual event was not a risk and did not leave you infected.
Despite that, you continued to post again and again regarding symptoms, even after having been told that symptoms mean nothing in terms of HIV.
Now when it seems you've finally "settled down" regarding this sexual event, you've back on the HIV bandwagon (so to speak) again posting what you think are symptoms regarding your fears that a nurse pricking your finger infected you with HIV.
This is, frankly, exhausting, both for you and for me. Shaunw84 is relatively new here and he/she may have the strength to go through what is likely to be many, many emails from you again over the same topic but not me.
Quite frankly, because you've been as persistent to them as you are to us in your fear that your son is HIV positive. They likely wanted to order ALL possible screening tests NOT because they believed he was HIV positive but because they feared you coming back later wanting yet another test done on him.
