Incision feels tight/ pulling/sore 4.5 weeks post op

The past few days when I get up from bed or in and out of the car or bending down, I feel like the incision is sort of tugging internally… I’m guessing this is probably scar tissue… I just started using bio oil on it… If anybody has any suggestions on what to do to ensure this heals properly because currently it’s sort of feels like I have a bump over the incision which I’m not sure if it’s normal
