i've spent the whole of today on this computer, doing coursework.
the posture that i've been in hasn't been so good. anyway, i have a REALLY painful shoulder. so painful that it's difficult to move properly or into a different position than the one i'm in now (kinda slouched).

i've taken 2 paracetamols but the pain returned within an hour. help me . does anyone ever get painful back/shoulders? is there anything i can do to help?? this is new to me and i'm not liking it.
