Hi. I'm a 43 year old very healthy female. I exercise daily and am training for my second half marathon. I started getting pain in my right pectoral area that feels like raw nerve pain last evening. It's since spread to my shoulder blade and now my entire spine hurts and I have an unbelievable headache. I am not stuffy and my throats is not sore. I don't think I have a fever but my body is very achy and tender. Does this sound concerning?
