Incision Pain

Hi all! I'm 7 days post orif for trimall and dislocation. Usual recovery with low pain level. My splint has loosened a bit to the point that I can shift my foot a bit. Heel has been hurting/burning so I'm lifting it up to take pressure off. My left/inside incision (staples) has started stinging/hurting the past couple of days. I'm thinking the splint may be rubbing over the incision causing the pain. Did any of you have this issue? Is it normal for incisions to hurt/sting after a week? I'm concerned about infection with recent increased pain. Post op appt is in 5 days to remove staples. Thanks for any input.
