My 8 Yr Old Son Developed A Flu In August,

My 8 yr old son developed a flu in August, seemed to be recovering then developed ' seal bark cough frequently, after numerous visits to GP, who said, croup or allergic asthma, he had bloods taken that diagnosed Mycoplasma pneumonia and recent whooping cough... He had 15 days is Erthromycin.. But still has frequent dry cough, fatigue, emotional lability. It is now November..! I have had him on fish oil probiotics etc... But worried he may have some underlying undiagnosed condition.. He seems to get bruises easily.. Some appear on his back... He does have asthma.. Has not had an attack for over 2 years, even though I did use flixotide for weeks when told he had allergic asthma.. With no change!
