My arm feels dead after b12 injection...why.

just had my first b12 injection at the drs and had in in my top right arm. when the dr put it in it crunched and he said i have good strong skin for it to do that and have quite soild arms fom muscle building. since the injection about 40 minutes ago my arm feels like i have been punched in it and feels heavy and sore and stiff to move is this normal after a b12. i am going to do my own b12 and folic from now on and maybe i shouldve chosen my leg instead....i didnt get folic this time as it wasnt needed. whats the secret to not having the injections not hurting when self administering them..
