I was withdrawing blood from a hiv positive client for viral load analysis,in the process I got pricked from the same needle I was using to the client.i started PEP after 6hours and finished the doses after 30 days.the following day I tested my hiv status and it turned negative.i was feeling weak and after four days I tested again and I turned NEGATIVE.later on I developed running nose,sore throat and dry cough that comes with pain at the chest.i took cetrizine,azithromycin and paracetamol and completed dose bt,the complains still persists.is this a sign that might be hiv positive?
