[|Human|] I had a very small but visibly noticable lump on or in the veing just down from my thumb, I pushed on it a few times it was soft and soon went away but now further up my arm but before my elbow I have an ache almost it feels like its bruised but it isn t. Any reason for this.
[|AI|]  Hi.based from your description, it could be any of the following: a cystic formation (possibly a tedious or ganglion cyst), a fibrous (fibrous tissue formation), lipoma (fatty deposit) or callous formation. If you are bothered by it, and it is increasing in size, affecting function of your hand, it is best if you consult with a doctor, for clinical evaluation. Diagnostics and management will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
