Hi there Dai
You have a large leg but still keeping your sense of humour.:-P
May I say Dai your a man who is very good with words,so why not use this gift,you must have a local paper!!!!,copies to executives plus,to paper,hate to say it,but works wonders,like a pain in there side.
Other option is to pay privately it should not cost very much you will need a referral from your doctor,trust me I know about these things!!
You need to get this fixed so you have peace of mind for your holiday:-)
There is some dispute between these departments,the NHS are trying to save money,and certain departments,do not have enough staff to maintain the service.( thats my guess ) do not quote me
On a personal level I would pay private,results the same day!!!
My best wishers to Wales you need to be able to walk to enjoy it,b-l-o-o-dy mountains.love Eve
