###Human: I have itchy rashes at the bottom of the ears with negative HIV tests. Do I need another HIV test? ###Assistant: Hi,  Welcome to icliniq.com. I have gone through the case. In my opinion, if you have no contact history for almost a year then there is no need to repeat all the tests. But first, you need detailed physical examination because there are different types of itchy red bumps and some of these are linked to sex and some are not. So do not go for all tests at once.
