swollen palm

For over a year now i have had a area on the palm of my hand which feels bumpy and swollen, it is around the base of my thumb.  As i am feeling the direction of the swelling i am convinced it seems to follow a muscle in my hand (flexor Pollicis brevis).  I am not experiencing any pain but if i extend my thumb as far as i can it generally just feels 'tight'.  i am unsure of what is going on and am afraid that eventually it could effect my thumbs range of motion.  Any ideas???
