[|Human|] Hi I had blood drawn on Tuesday and when he put the pressure on afterwards I felt a stabbing pain, worse than when the needle went in, I applied hard pressure for as long as he asked me to and a plaster was applied. For several hours afterwards I had a stabbing pain and couldnt bend my arm. 3 days later it still aches and the bruise is large and dark and covers a large area of my arm along the vein and round to my elbow. Do I need to get this checked?
[|AI|]  Hi, Welcome to Chat Doctor, You must have given blood for some investigations, normally blood is with Chat Doctor. You applied pressure, and it was sealed with plaster, do not worry sometime some blood may leak and causes local bruise and inflammation called thrombophlebitis. I presume pain must have subsided by now, but you can use cold fomentation to give some relief. Usually it gets resolved in few days, but you can apply local heparin ointment or gel like Thrombophob. I am sure this will disappear completely in few days and your arm movement will also be normal. Take care Good Luck.
