just been for my b12. got there nurse said i looked very well considering i only had my HEART BYPASS 4 weeks today , i explained it was gastric bypass not heart she said ohhh i didnt read the whole letter just glanced bypass asumed it was heart OMG i thought. then she explained she cant give me injections as it has to be the doctor first time and that i get it gradually 2 to 3 times week for first couple weeks then next time it will be just one injection. panicking with fear or needles i informed her i was told it only one injection and nurse did it. she said please excuse me i need to ask advice from receptionist . sat waiting could hear her asking if they could check procedure info and will re schedule my appointment . HOW shocking is this lol . i sharp left. SO is it a one jab or is it gradual jabs anyone know ?
