my throat is sore, especially near the top. both sides of my neck hurt when i try to turn my head or when i press my fingers against the skin, especially behind my jaw and below my ears. the left side of my sternum is what's hurting the most; when i lean forward, push against it, stretch my arm down, sit slouchy, or breathe out too deeply, there's a sharp stabby kind of pain. it began this morning when i woke up.
any idea what this could be? :\
