Ok...I had some trouble pinning today, couldn't get through the scar tissue. I attempted to go in a few different places, took 3 times to get it right. Used a new pin each time. Part of my right quad is swollen and tender/sore. There is no redness, warmth or any other odd sensations.
Is this just trauma for being stabbed too many times or is it something to worry about infection wise?
I followed standard injection protocol. Alcohol applied to vial and injection site. Swapped pins. Aspirated, etc.
