Hello Fiona... thx for your reply... we had our physio over yesterday and checked him out, he found he was badly tied up in the offside back.. gave him some injections and manipulated hid back , neck and legs.... he just need some time off so he'll be taking it easy for the next 3 weeks.... as soon as he finished with him ,he was getting into things as usual .... again thank you for your reply.... regards.... steve
