IM stuck on getting a skin biopsy. I have the scalpel but when I take it up to the arm it dissappears. How do you get the biopsy. ive talked to the patient I have the scalpel but the item is still in red it has not changed all the other rooms are done so i can't get any other items. when I hit the hint button it just circles the elbow of the patient. I can't get past this part. I've tried scraping it but can't get anything to work. can someone help me with this???
