I ve felt tired all the time for the past few weeks, even after a whole nights sleep, i wake up tired and feel tired all day long. I ve also been feeling really achy over the top half of my body, shoulder/neck/upper back ect, and now I ve got a cold: sore throat (affecting my chest slightly) and runny nose. I m a student and really need to get on with my work but I just don t feel up to it.
