Answer
Hello Cameron,

Can you post a picture of that wound for me?  That would help.  
What are you doing to keep it clean?  I would suggest using a diluted betadine, along with an antibiotic ointment such as neosporin or polysporin if you have that type of ointment in Ireland.  
What type of enclosure is he in, could he have hurt himself on a sharp edge in the tank perhaps?
Are you using a UVB light for him?  If so, what type, a flourescent tube bulb or a compact/coil light?  What brand is it?  What are the temperatures in the tank, & what is the humidity?  What type of thermometer are you using, a stick on type, a digital probe or a temp gun?
What are you feeding him now?
