Description
This gives the muscle time to accommodate the fluid without causing that sharp, burning sensation many fear

Won't diagnose any condition but if raised, will indicate that further investigations are necessary (thinking here - has your GP ruled out inflammatory bowel disease as a cause of your B12 deficency?)
