I injured my knee 2 months ago when a board with a rusty nail hit it and punctured the skin. I believe the nail hit the bone as well. It swelled up for one day but after that it went down and was fine. Today, after 2 months, I just noticed that a small (big knuckle sized) lump has developed in the same location. What would cause this lump to appear after 2 months?
based from your description, it could be a fibrous tissue formation on the previous site of injury. it is similar to scar formation, only coming from the inside. it is best if you consult with a doctor, preferably a general or an orthopedic surgeon, for clinical evaluation. other tumor types must also be ruled-out. diagnostics (such as imaging and tissue biopsy) and management (medical and/or surgical) will be directed accordingly.
hope this helps.
good day!!
