@jdmdev1225 Welcome to Mayo Clinic Connect! I haven't had any wounds glued shut, but my thought leads toward the fact the serous fluids that would normally be able to be released, cannot get out. So there might be a pocket of fluids there? Any underlying scar tissue might be preventing that release, and creating the bump and pressure.

Does this sound plausible to you? What was the reasoning to go with glue rather than stitches? You say this was after a range incident. Perhaps clearing a semi-automatic pistol and slide caught you, tearing up the side of your index finger?
