My reaction has been about the same, but I seem to be having a bit more bleeding lately too. I was thinking that I just wasn't being quite as careful since I've gotten more comfortable with injecting manually.
I do have itching...sometimes for up to a week after but the SS nurse also told me that, this can be perfectly normal. It doesn't happen all the time and when it does it is more so in my arms than anywhere.
You can reduce the likeliness that blood or fluid will backflow from the injection site by delaying withdraw of the needle. Count to ten AFTER all the fluid has emptied out of the syringe. Then hold gentle pressure over the site for a few moments. Sometimes this helps.
You also want to make sure the air bubble is injected after the medicine. It forms a seal of sorts. Do NOT remove the small bubble of air from the syringe before you inject. The manufacturer left it there for a reason (at least one).
Itch intensity varies from time to time. For me it always seems to increase when my immune system is most active--like after immunizations. We all also have specific site locations that are more prone to reactions of one sort or another. Thighs are common but so are arms.
