I got infected with COVID-19 for the first time on 11/24/2022, and possibly again on 9/1/2023, with a vaccination taken on 1/2/2023. I noticed IgM antibodies, but I'm unsure if they are from the recent infection, vaccination, or an earlier one. Can you explain the duration IgM antibodies typically last after an infection or vaccination, and how to differentiate between the sources of IgM based on the dates of infection and vaccination?

The other day I was walking through a grassy patch at night in the city. After getting back to the sidewalk I felt a little prick but I’m thinking it could’ve been the fibers from my socks or my anxiety imagining things. I’m concerned about if I could’ve stepped on a heroin needle. I had sneakers on and examined my shoes and socks to see if there was a needle and I saw nothing. I also didn’t see any blood on my feet. Do you think I should get tested for blood-transmitted illnesses such as HIV or HCV?

I have a lump near my groin area. I noticed it yesterday on my left thigh near my testicles. The lump is not itchy, but the skin around it is loose and filled with fluid. It's not hard, and when I tried to slice it open, blood squirted out. I'm 22 years old and not on any medications. What could this be, and what should I do?

I took apple cider vinegar along with my metformin and now my blood sugar is 303. How can I reduce my blood sugar quickly without going to the emergency room?

I think I found new marks on my penis. I'm concerned about these lines and bumps that seem more defined or irritated than normal. I've also noticed slight tingling and random sensations. Are these symptoms of something serious, or are they all in my head?
