Hi, I played Archery during this weekend & everytime I release the arrow, the string hits my arms. As this happened for quite a few times & since the pain was less, I just kept going,,, Today, after 2 days I noticed that there is a blood clot scar mark in light purple color on my arms!! Do u have any idea how to remove this scar ? Also there is no injury in my arms, just this blood clot alone.
