Thanks for all the comments. Im still waiting for my mri scan appointment to come, so until then theres not much I can do.
Im due to go back to school next week. I know that its very unlikley that anyone will ask how I am apart from close friends. Its just treated as an inconvienience by others.
Also, recently a friend at work had to have an op on her eye. A collection was made to get her flowers. Another colleague is an alcoholic and he fell downstairs when he was drunk and broke his leg and he was sent a basket of fruit. In both cases you can see what is wrong with them so they get sympathy. It just annoys me that because you cant see a back problem it is automatically thought you are putting it on. I dont want sympathy but it would be nice to have my condition acknowledged.
