I Went To Plasma Center To Give Blood Plasma. The

I went to plasma center to give blood plasma. The person doing the process was new with their certification. The machine broke when they stuck me and it took 10 to 15 min to get the process started when they tried to return my blood back into my arm it would not go. Now I have this bruise will this discoloration go away and will my arm be ok ? It feels better but still is sore it's been 4 days sense plasma donation
