There is a hard boney lump on my hand, what does this sound like?

Couple possibilities: Most bony lumps could by related to bony growths ( osteochondromas or exostoses) that project off bone near joint. Osteoarthris (arthritis with age) can produce lumps around joints in fingers. Bone spurs usually occur near joint and can be in distal fingers or around knuckle. .Ganglion cyst ( fluid filled) usually back of wrist adj. To tendon may be soft or hard. Concerned see physician.

Bumps and lumps: In the hand vary in what they are by location, size, "feel" ( there is no subsitute for having an experienced hand surgeon put their hands on your hands) and other factors. Still the most common bump or lump in the hand is a ganglion, a foreign body inclusion cysts or a bone spur. At times they feel hard, even a ganlion if it is small and coming though a retinacular structure or a finger pully.
