Hi there ~
You most likely do not have any infection related to the HIV
. However it may be best to get testing done as soon as possible to relieve your anxiety
about the same. I would think that the nasal congestion
a week later is also not related to your exposure to the body secretion, if any, that may have happened during the procedure. I hope this helps relieve your distress about the whole incident (where you do not know the status of the patient and mention that the patient was suspect HIV neg).
Take care and have a lovely day !
