I had my six injections about four weeks ago. I've had a couple of 'events!' With symptoms I experienced before the injections which I was told were normal. However, this week, I woken up with an incredibly dry mouth - it was soon over at the beginning of the week and has become much longer lasting. Today, I feel quite unsteady and my mouth feels like is has had a holiday in a desert. I don't have a red or sore tongue which supposed to accompany the dry mouth so are my symptoms B12 related and therefore to be tolerated or do I need to get back to the doctor? Any comments/advice would be much appreciated.
