So, two days ago I was doing a workout by lifting weights. I changed the weights from light to heavy and did this for a while. Today, I noticed very small dots on my arm and am really scared over this. I'm scared over this because I've heard that a lot of people who have leukaemia have purpura or petechiae. They aren't that clustered together and they are quite faint (I can't really see them when the light isn't shining on my arm). I tried linking this to the workout I did, but I'm stressing over how the workout was two days ago. Wouldn't I have had the petechiae right after my workout? I also had a blood test in January or February, to check my thyroid and everything was fine, including my iron levels.
