Friend maybe has throat bug

Hello, well today an old friend was telling me he was sick, he has a cough for about 4 months now. So he went to the doctors and (well i live in mexico) and they just said " we dont know what it can be, he's anti-biotics take them for 2 months and comeback for studies" i got really mad so i'm trying to figure this out and well the only thing i can think of is GAS disease.

His symtpoms is basically just sore throat nons top for the past 4 months and every now and then he will get "pus pillows" sorry not the best at translating

Hello and hope you are doing well.

The other causes for long term cough besides asthma are GERD and post nasal drip from allergies. GERD is gastro esophageal reflux disease where the stomach acids come back into the esophagus and spill into the wind pipe causing cough. Treatment with antacids will help neutralize the acids. Post nasal drips can occur with sinusitis and throat infections. Giving up cigarettes will abolish smoker's cough in 90% of people. He could talk to his GP about the other causes for cough in the meantime he could try warm salt water gargles and breathing exercises.

Hope this helped and do keep us posted.
