I have a slight lump on the top of my hand in the area of the adductor Pollicis Brevis Muscle. It is slightly painful (not too bad though). FYI I play a lot of tennis and am a personal trainer so I use my hands a lot. Could it be arthritis ? (I do not think it is ganglion since I do not believe it is next to a joint or tendon.) Should I get it looked at ? What could it be?
Hi it should be checked by x-ray. If not from bone, then may be from soft tissues. Wait and watch if it grows or produces symptoms or interferes with movement, then consult doctor for evaluation. Meanwhile apply Voltaren gel and use wristband or strapping. Thanks
