In the worst case if they have reused the needle, does sore throat & cough after 8 days sound like ARS ?
If the needle is reused how much is my risk ?
Can i continue unprotected relationship with my wife ?
Concur with the advice of Rubywitch.
Needles are only reused in back alleys. Professionals NEVER reuse needles for safety (health) reasons..............YOURS AND THEIRS!
Your sore throat and dry cough that lasted 8 days sounds suspiciously like the common cold.
They are NOT symptoms of ARS.
NO RISK AND NO NEED TO TEST
