Injury Very slight limp

This is Jeni, she’s one of my four year old piggies. On Tuesday I noticed that when she walks fast or runs (Yes she’s still able to run), she slightly limps. When she walks slowly there’s not a noticeable limp. She does sometimes lift her front leg up and puts slightly less weight on it, but not all of the time. There’s no swelling anywhere, nothing bleeding, and she doesn’t get bothered if I touch it. It’s now Thursday night, and it’s still about the same. She’s acting completely normal, even got a bit excited earlier and gave me a little popcorn. As the weekend approaches, I want to know what I should do, I work tomorrow and will likely be unable to take her to the vet. I wanted to know if it’s even necessary to take her to vet being that it’s so mild that I wasn’t even sure she really was limping at all at first. She did jump from my arms a few days prior to noticing this, it wasn’t a big fall, but they do have tiny little legs. I will be honest, I have still been letting her out of the cage to exercise twice a day, so I have not been letting her rest it likely. Also, I do have some Metacam from my other pig from when she hurt her foot.

all advice is valuable, I would especially appreciate hearing from @wiebke as I’ve read your posts over the course of a decade. Thanks all.
