Hi OppOnn,I can't really say for sure your cough is due to GERD but a cough can be a symptom of GERD, specially if you get it more after eating or lying down.I occasionally wake up through the night with a slight cough due to irritation in my throat from the GERD.Lying down after eating is a big no no if you have GERD too, that is why you would feel better if you don't lie down for at least 2 hours after eating. I NEVER eat late myself, usually not for at least 2 - 3 hours or more before bedtime anyway, or I have more trouble with the GERD.I suppose it is possible to have GERD and Chron's at the same time too. I have IBS, GERD and a hiatus hernia all together, so I think it would be possible to have Chron's and GERD. I asked my doc recently about all my digestive probs and he said if you develop one digestive prob you are more likely to develop others, and things like GERD & hernia etc do seem to go together.Anyway, hope that helps some. I have also included some links below to medical articles about GERD that give more information about symptoms, treatments etc that you might find helpful.Re the strep throat tendency, it might be related to the GERD, after all if you have some reflux (acid) burning your throat it could feel sore from that or leave you more susceptible to strep throat bacteria getting in.Hope you feel better soon. http://www.mydr.com.au/default.asp?Article=3351 http://www.mydr.com.au/default.asp?Article=3353 http://www.mydr.com.au/default.asp?Article=3352 http://www.mydr.com.au/default.asp?Article=3426
