What is this large bump on left tip after revision? Would you expect it to look like this over 3 weeks after revision? (Photo)

I had rhino over 1year ago. I was left with a bump on bridge,deviated septum,interior scar tissue and 'bump' on left tip(Maybe Bossae?) I had revision surgery by same surgeon over three weeks ago- this included septum spreader grafts, shaved nasal bump, scar revision & a graft on the 'bump' on left tip. Over three weeks after revision there is a very prominent hard 'lump' on the left tip. Surgeon says swelling but that doesn't seem correct. Please advise? would you be concerned and what is it?
