It was about five months ago now i went to my doctors for the season flu, and swine flu immunisations, i also had more immunisations a few weeks ago in school. the thing thats worrying me is that i can still feel where the injections went in and my arm aches quite bad when i lift my arm up above my shoulder. This was about five months ago and i though the acheing would go away but it has not, will it ever go away?
