Thank you for the advice. Yes it’s the Hand that is the issue as it states it’s a bar no matter how significant. unfortunately it’s a small surgery so only 3 GPs and no specialists. The doctor has said he’ll have a letter ready for me on Monday so I’ll see what that says. Hopefully it will help.If you're past the 3 years without reoccurrence your appeal should be upheld. They might be a bit iffy with it being on your hand as I believe there's a special note in the JSP950 regarding it.
If you have a larger GP practice (more than 4ish GP's), there should be one on staff who has specialised in dermatology who's opinion might hold a bit more sway. Just be prepared to pay the practice a fair amount of cash for a single paragraph letter to post off with your appeal.
If you need any help with the particulars of appealing, send me a PM and I should be able to help you.
