I have been feeling a sharp pain where in my lower neck/upper back and shoulder. The neck pain has been there for a few days and the shoulder pain has been there for a long time. I just started my first workout program (Blend), but I have been working out intensely before I started the program. Should I stop, until I feel no more pain, or push through and maybe the pain will disappear by itself? I can’t tell if the pain is from sitting or sleeping weird or from working out. Help!
