My 12 Yr Old Was With Her Old Sister 3

My 12 yr old was with her old sister 3 weeks ago who had bronchitis and positive for mycoplasm in her blood work. This Thursday my 12 yr old developed a loose cough which has progressed to a sore throat, chest burning and head congestion. She played softball today all day- using her inhaler from a previous illness and taking Mucinex and IBU Q 4 hours. No fever- although she has had IBU in her continuously. She was SOB
with exertion and had to use inhaler after running with fair relief. No wheezing note. She feels just plain miserable. No body aches. Just curious if this could be bacterial or viral. She blows yellow/green in the morning but clear runny nose all day. Thank you
