Condition analysis: It takes a long time to repair the soft tissue injury after trauma, especially the fingers with rich nerve endings. In addition, because the repair of trauma will mainly focus on scar tissue, there will also be proliferation of fibrous tissue inside, and a palpable lump will appear at this time, which is actually an internal scar.

Suggestion: the internal scar will be absorbed slowly over time, and it will be uncomfortable in a short time, and will be repaired by itself later. It can be accelerated by hot compress. If it is only manifested as pain and soreness caused by local pressing, it will be fine slowly, without medication.
