<s>[INST] Recently I knocked the top of my thumb between the thumbnail and the first joint and it bleed yellow with some light red blood. I called my GP s office and ask why and was told that they had never heard of such a thing. then day before yesterday I was scraping a small what I was a bump and when I did the blood was light red and dried to be the color of orange. What could cause this and should I be concerned? [/INST] Hello, I have studied your case, Due to blunt injury there can be hematoma collection. The bleeding that occurs result in hematoma collection. Over a period of time, as hematoma resolves it cause local skin symptoms around the hematoma. Continue ice application, and thrombhophobe ointment may help and take rest. If required you may need to do blood investigation for prognosis and recovery. Take precaution to avoid infection around hematoma. Hope this answers your query.
