permanent blood blister

I have this weird blood blister like thing on my right  hand.  It has been there for maybe 5 years and now my parents are pushing me to have this thing looked at.  I think I got this airsofting, but I'm not to sure about how I got it.  It protrudes out and probably has gotten bigger.  I looks like a blood blister except its pretty deep.  Once during basketball, i got a cut and it opened, it was like black tissue and nothing more.

Hello,
From the symptoms it can be a blood blister or pyogenic granuloma. Blood blister forms when subdermal tissues and blood vessels are damaged without piercing the skin. It is commonly found on hands. Elevate the hand, give rest to the part, apply cold compresses, soak the blister in Epsom sale and keep the hand bandaged so as to avoid its rupture. If the blister breaks, quickly rinse the area and apply an antiseptic such as neosporin. It is not recommended to break a blister because it may often lead to infection.

If the symptoms worsen or persist then please consult a dermatologist and get pyogenic granuloma ruled out.

I hope it helps. Take care and regards.
