Hey, I'm a 15 year old male who currently has strep throat, along with asthma, and pretty bad allergies. I'm currently on penicillin for my strep and have been on it for almost a week now but haven't got much better, so I started looking up other things it could be and started thinking about lung cancer, because my chest has kind of felt tight/achey and I've also had a little hard time breathing, I asked my parents about what they thought and they said I shouldn't worry about that, and that it's from everything else right now, so I was trying to see if anyone had some ideas. Thank you!
