<human>: After I had fractured my right index finger a couple months ago, when it had healed it left me with a tiny lump on the bottom left of my proximal phalanx. The lump is only visible when my finger is bent, when it is straight nothing can be seen. I m not sure what it can be. Thanks.
<bot>: HI. Thanks for your query and an elucidated history. The small lump on the bottom of proximal phalanx can be due to the following factors:-Callus, the bones' effort to heal the bone properly-sometimes takes time to get re-modelling or resorption. - Tenosynovitis on the tendon or the capsule of the joint van be prominent as you have mentioned. I would recommend the following: Take an anti-inflammatory tablet in proper duration and proportion. Hot water bath to the affected area were, the water being a strong solution of common salt, use the same solution again and again in spite of being dirty later.  I hope this answer helps you get a clearer picture, proper diagnosis. This leads to a proper treatment.
