I Had An ABG Drawn About 4 Days Ago (came

I had an ABG drawn about 4 days ago (came back normal) and I experienced significant pain in my arm, wrist, thumb area for about 4 hours. It bruised a good three inches down the middle of my wrist. The bruising seems to be healing but I have a small tender knot where the ABG was drawn. Is that anything to worry about? I felt that I bruised and experienced pain because the tech did not hold pressure long enough nor hard enough. I just worry about the knot being a clot.
