Thanks everyone, yeah i will be careful, I often stop if there is a problem. Mind i didn't get the nickname stranded turtle for no reason!
If the pain and general achyness is still with me when we get back from holiday, the first thing i will be doing is phoning the doctors for an appointment. I really want to know what is wrong and get on with driving!!!!!!I want my independence!
Plus I now have work worriead, so i guess it will be better all round if we knew what it was.
