I've had this sore throat, which developed into a persistent cough which that just doesn't seem to go away. It's been dry, tickly, and no wet. It's been lower chest/stomach, back if my throat and now middle of chest cough. It's been 6 weeks, I start to feel better and then it comes back and I begin to lose my voice again. Today my right arm has started hurting like repetitive strain type pain, hurts to move it and feels very week. When I cough it really hurts 😔 I feel like I'm falling apart..I seem to feel better after rest and then go back again.
