Swelling on top of foot

4 months ago I had a modified Youngwick osteotomy.
Recovery has been going well with wonderful range of motion.
I have been discharged.
My only problem is persistent swelling on the top of my foot . If you look down on my foot it is located under the 2nd and 3rd metatarsals.
It’s not too painful.
Just wondering if this is still part of the normal post op recovery or something I should keep an eye on.
