Maybe a cyst: This could be a tendon sheath cyst. If so, it can sometimes get stuck in the sheath and cause the "trigger finger" phenomenon. Read about trigger finger and see if the location seems to fit with yours. This can be treated if needed.

Ganglion cyst: Commonest lump in the hand is a ganglion cyst. See a hand surgeon and s/he can decide if that is the correct diagnosis and treat you appropriately.
