Hi ! Good evening. I am Dr Shareef answering your query. From the history, it seems that you might have sustained some kind of trivial trauma while cutting woods resulting in oozing of blood in the tissue forming a collection of blood (hematoma). Usually, small collections of blood get absorbed of their own. However, this may not happen in cases where the blood clotting is hampered by the intake of blood thinners as is in your case and the same might also get infected causing more pain due to an abscess. If I were your doctor, I would consult your physician who started your blood thinning agent for consideration of discontinuing these medicines for some time till it heals up.If it does not even then, I would refer you to a general surgeon for a clinical examination and further management. 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 health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef. If I were your doctor,
