Thanks for writing in to HCM.
I read your question with interest & thanks for the detailed history.
No Phlegm is NOT a sign of HIV
Fingering your ex-girlfriend if there was no contact with blood or blood products will not have caused an infection with HIV provided also your fingers did not have cuts etc.
If so anxious, may be best if you did an ELISA
for HIV & rpt the test after 6 mths & clear your doubts. Alternatively, i recommend always a DNA-PCR
test & this will help reassure you.
Good Luck & Godspeed & Do always practice safe sex!
