Hello, I am concerned regarding a lump in the area of where an I.V. was put into my arm when I was sent to the ER. There is a 2 inch bruise surrounding the area and the vein feels engorged behind the small lump in my vein. The IV was put into the vein between the forearm and bicep (elbow area). My hands have recently felt cold and I have been experiencing tingling sensations. I am concerned I have a blood clot in my vein which could potentially be dangerous.
