but if you have any symptoms at all go back for another shot. sometimes it takes two doses to make the symptoms go away.
Actually, it has been said on MedHelp by the seasoned posters (longer than me) that testing again less than 30 days after treatment could very well end up in a false result. It is best to not test for at least 30 days after treatment.
i would wait a week and test again as a precaution.
