Bumpy/enlarged/inflamed gum 1 month from oral surgery

[dante4x]

hi guys, i had an oral surgery in my lower left about 4 weeks ago to remove an infected root-canal tooth, and ever since then, the gum tissue around that spot feels bumpy/inflamed when i'm feeling it with my tongue. when i compare the surface of my gum tissues anywhere else in my mouth like on my lower right, everything feels flat and normal. you would think after 1 month of recovery the gum or spot should return to normal but it hasn't. should i go see a periodontist to have this checked out? i'm very conscious of it during the day and it's annoying me quite a bit. thanks.
