I ve been an emotional wreck the past couple of days. I ve never worried about these things but for some reason, things have been bothering me. 7 days ago someone from the diagnostics lab came to my house to give me a urine and blood test. I m getting life insurance so this was required. The person was very late and on top of that, I think the person was very sick as he was coughing all over the place. At this point I was pretty aggravated and he proceeded to take out a box and take out a green plastic needle (used to draw my blood). I was a bit annoyed at this point but, I don t really remembering there being a plastic sealed wrap around the green needle used to draw the blood. The needle didn t look the typical needles used in hospitals (clear). It was more a blocky plastic green needle. My worry is that I don t recall seeing a sealed wrap around the needle and the possibility that this may be a used needle? Is it possible to get infected if they re drawing blood from me? I don t know if it s coincidence or not but it s been about a week now and my throat feels very stiff and my breathing is very shallow. I find myself not being able to take deep breaths. I find myself gasping for air alot. I always go to the gym and going this week has left me very winded and gasping for air. I don t have a fever though.
