Can Varicose Vein Cause Pain In The Sole And Heel With Swelling?

I have a bruise on the outer side of my right side of my foot and pain in the sole, nearest the heal and including the side where the bruise is. It s painful to walk on, and while I have iced the area incessantly since first noticing the pain, the area has become swollen and hard to the touch, and I can also see the veins inside the swelling area are noticeably larger. It hurts more like a burning, like I got hit with something, or like there is infection. The color has stayed somewhat consistent with bruising, but I haven t tripped or fallen lately. Could it be a busted blood vessel or a varicose related issue? Any advice would be appreciated and helpful. Thank you so much.
