I had a muscle biopsy in my forearm a week ago at the mayo clinic & i still have swelling & bruising going down my forarm & almost to my?

Still normal: Bruises from surgery may last a few weeks. Watch for the bruise to shift colors from typical black and blue to yellow, red and green colors near the edges. This should assure you the blood that leaked into the soft tissues is being dissolved and absorbed with time. You can use alternating heat and cold therapy to help dissolve it. 5 min. Ice and 5 min. Hot moist towel for 3 cycles- do 3 x a day.
