Thanks to everyone for welcoming me to this site. I want you all to know just HOW GLAD I am that I did! It seems my question that I thought was silly could in fact be quite serious!!! My Doctor has already booked me in for a test to see if it is spinal fluid. It seems that if it is and I hadn't done anything about it it could have been quite serious. Hopefully it isn't but at least I will have it checked.
