What could cause a lump in my finger?

Answer by  mouscelia (170)

There are several possible causes. You may have a seed wart, a blister, a pimple, an infection, or you may have a bug bite. If the lump is very large, swollen, or painful, you should see a doctor right away.

It could be arthritis of the fingers. Lumps and bumps frequently occur at the last joint of the finger or thumb due to wear and tear arthritis (osteoarthritis). While the lumps on a finger might be nothing it is best to go get it checked by a doctor for a true diagnosis and correction.
