So I went overseas nearly over 2 months ago and i dived off a boat into a really shallow reef. I scraped my ankle on coral and when i originally did it, it really stung. However now it doesn't hurt though it is still purple, is it just a scar or something more? When i was overseas as well i fan into the corner of a chair and hit my shin, i still have a bruise from where it is and it hurts to touch. However it doesnt hurt to walk on, should I be worried.
