Hi, I ve been feeling sick for the past 36 hours with an ear ache, sore throat , runny nose , high temperature and aching, weak limbs. However, pretty much every time i get sick, my back hurts as well. I was just rubbing the painful area and it feels mildly swollen. The pain is in the upper middle part of my back, mostly by the spine . I m worried and don t know whether this is normal or not.
