<s>[INST] I have noticed my left hand (Palm area) being sore past few days now. Today put on some hand cream and have found a lump, centerized in the palm of my hand closer to my wrist. It is sore when I push on it. It s the size of a pencil eraser. It does moves around and does not feel hard but it is definitely a bump and quite sore. Should I be concerned? I do not remember injuring it. [/INST] Hi.based from your description, it could be a cystic formation (tedious or ganglion type), a lipoma (fatty deposit) or a fibrous (fibrous tissue formation). These are all benign lesions. Other lesion types must also be ruled-out. A consult with your doctor, preferably a general surgeon, is best for clinical evaluation of the lesion, especially if it bothers you now. Diagnostics (such as X-ray and/or ultrasound) and management (medical and/or surgical - excision) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.  </s>
