[|Human|] Hi there. After I had my blood drawn, I developed a little pea sized lump on my arm at the draw site as well as a little bruise on the area of the lump. If i touch it, it hurts pretty bad. Is this something to worry about? What caused it and how can I make it go away?
[|AI|]  Hi. Thanks for your query. Noted the history and understood your concerns. The blood is usually Chat Doctor. The puncture is done by a needle and may cause extravasation of blood causing a pea sized lump and bruise above it. I would advise you the following in such situation wherein there is a formation of a small hematoma. Stop fondling the hematoma as it may delay absorption and self-healing. If of recent origin, local cold compresses for few fours may help. Leave it alone then. May take anti-inflammatory if there is pain or tenderness. Stop worrying as this is self-limiting condition.
