That does look damaged. I'd keep an eye on it but not worry about it too much. It's possible that it will return to normal after the next shed. As long as the damage doesn't start looking worse or start affecting the areas around that spike (indicating possible infection of some kind), then I don't think it will cause much issue.
Thank you for replying , I’ll keep an eye on it as suggested , I’m guessing he knocked it yesterday after we put him back in his clean Viv !! He goes a bit crazy after we have cleaned it out !!
That's a possibility. If it's just a bit of damage from bumping into something, it's likely to just heal up or at least not get any worse over time. Shouldn't be too big of a deal.
