When I was born there was a mishap at the hospital. Long story short I got burned by concentrated glucose on my ankle. It burned me really badly and gave me a touch of nerve damaging. Even though it's been 27 years later sometimes it hurts. Inside feels like it's burning or there's this ache I don't get it. Some one told me that's scar tissue still growing. Can scar tissue still grow after this many years? I just want to know if it's something I should be concerned about or is it really just scar tissue growing in an old scar.
