Hi, 18 days ago, I was possibly pricked with a needle whilst at a rave.. Recently, I have found my submandibular gland on the left, to be hard, and larger then that of the right. Both are moveable. I am worried sick that it is HIV , I have also had pains in my head which lasts for a few seconds, coming and going for the past few days. Furthermore, I have had abdominal and some muscle pains around the arms and legs. I feel like I m going crazy having to wait for the window period to close. Does this sound like ARS? Is there any way I could get tested any time sooner? Thanks for the help.
