Please give me advice. I went to a hospital and I'm not sure if they used a used needle on me. On 20th day, I had a test to make sure. The method used is Ag/Ab CMIA. Around 23rd day, I started experiencing several things. It started with some red bumps on my chest. Then an ache like a small pinch in my throat everytime I swallow. The next day, I felt stomach ache like cramps. And then I felt pain on the left side of my neck near my jaw and ear. I tried feeling it but I didn't feel any lymph nodes. And then my left eye became painful.
Do any of these thinks like the pinch in my throat, stabbing headaches, and red bumps on my chest, look like they can be related to a used needle being used? Can I rely on the results of the CMIA test on Day 20?
