Does anyone know what this weird bluish blackish spot on the sole of my foot might be? It’s making me a bit nervous. I said earlier it’s been there for 2 months. I just touched it now and it’s not a blister there’s no fluid that I can see or touch. It doesn’t hurt to touch or walk on. I was actually walking barefoot today in grass and on the parking lot a bit. But I’m a bit nervous about it honestly. I’ve had marks and stuff on me but not for 2 months and they were always blisters.
