Help could I have HIV ?

So 3 years back I got my belly button pierced at one of the local tattoo shops. The guy who did it followed all safety precautions. Like he where gloves, washed his hands and made me fill out paper work. The only thing is he didn't open the needle right in front of me. But from where I was standing It looked like everything was coming out of new rappers. After I got done he explained how to clean it and gave me a paper with directions on how to clean it and his card. when we got in the car my sister said that he did it wrong and that she didn't feel he was a good piecer. About three weeks later I came down with a fever and sore throat for about 2 days and 4 days after that I developed 3 mouth sores and burning lips and the inside of my nose would burn. The mouth sores and burning lips came back every mouth for about 4 mouths. The thing that is bugging me is that i swear i have hiv. I have gotten sick a couple of times over the 3 years and I always blame it on the HIV I think I have. I have had blood work done and doctors say everything looks normal. And for a long time I thought I was until today I got up with a swollen glade in my neck and groin and i still blame it on the body piercing i got years back. I have read that nobody in the history of body piercing has ever been infected with HIV. But that doesn't make me feel better. I keep thinking what if he had HIV and gave it to me on purpose or what if he opened all new things expect the needle and used a dirty one just cause. I know places like this have to be checked by the health department and things like that. Also I am a virgin so there are no other risk. My question is should I worry or am I over reacting? Should I still be tested? Or just let it go? Are there other reasons why your glandes can be swollen without it being HIV? Do any of my symptoms sound HIV related. Thanks
