[|Human|] I developed a roudish, small lump on  top if my hand, after doing nothing to injure it. The lump sort of rolls around but is either atop a vein...or, in it.  This happened over a10-min period...suddenly, lump appeared and became purplish in colorish and stingy. Im worried about developing a blood clotting disorder.
[|AI|]  Hi! Good morning. I am Chat Doctor answering your query. Although it needs a clinical assessment, from your history, it seems to be a hematoma and if there is no history of any injury, and if it increases in size, you have to get it assessed by your family physician or the treating physician to rule out your suspicion of a clotting disorder with related investigations. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
