Help me. I'm worried I might be sick?

I suddenly remembered an incident that happened in the order of 1 1/2 years ago. I was at a public house, and the next morning, I notice some sort of mark on my middle finger. I'm not sure what it be, but it seemed and feel like a pinch, or a puncture of some sort; it be reddish and it seem to be pretty deep contained by the skin. It went away after somewhat while, and I didn't really think anything of it since. Now I'm compassionate of freaking out because I'm worrying if I might have accidentally pricked myself next to something (like a needle).
I know that there could be a much better explanation, but I dunno I'm worried. I don't infer I've had any strange symptoms, but I notice that I have these small little pimple approaching bumps on the back of my nouns. I've had them for a while; I can't remember when they showed up, but it might own been track before or around equal time as this incident. They could as easily purely be a skin condition. They don't hurt or anything, but they're still there.
Sigh please facilitate me. :(Help me. I'm worried I might be sick?
I think you are overthinking it- did someone stick you etc or possibly did you just hurt your finger--probably not and issue at adjectives a billion to on e that there is - but if it willhelp improve your mind go achieve an hiv test- it will soothe your thinking
just dance see a Doctor
Stop worrying. If it helps walk to the doctor for a blood test concerning the disease you are worried more or less. I am 99.9998% sure its nothing.
if within are no apparent signs or symptoms of condition that are bothersome for the last year, I would simply chalk it up to something you did stupid and try not to get so worthless that you can't remember what happen. Life little curriculum!!
