Hi. I'm 19 years old and 2 days ago, I had a bad sore throat. Because of that, i also had a fever. I ate porridge and drank warm water and my throat gets a lot better the next day. I dont have a fever anymore. However, although my throat didn't hurt anymore, I've started coughing a lot and today, when I sleep, I keep waking up because I felt uncomfortable. As in my upper back hurt. It's not painful. Just that uncomfortable numb feeling. It only felt better when I lie sideways or sit up. I'm wondering is it pneumonia? But again, I'm not extremely breathless or anything. Please help.
