I fell over around 2 months ago and was covered in bruises, including a really bad bruise on just under my knee cap. The bruises have healed, and the one on my knee you can't see but it still feels puffy like there is fluid trapped under the skin? It really hurts/feels tender when I kneel on it as if it's still bruised, but when you look you can't see a bruise.
It's been 2 months. It's such a minor thing that I think I should just ignore it and that it will eventually get better? I'm in my 20s and in good health for context
