Gail:
Welcome to a plethora of awesome information to help you through. There are so many threads of information and people that have been there, willing to help. I am going through an issue right now (Minute in the big scheme of things) and I tracked board information all the way back to 2006, and it all helped. As far as the "Burn" I had an issue with most everything following treatment. It will ease up with time. Dairy was an enemy for a long time and I learned everybody's different as there was a lot of posts here talking about the "Calming of dairy (milk, cottage cheese, Ice Cream, etc), so give it time, experiment, and be patient, but DON'T GIVE IN OR GIVE UP!
Keep drinking, eating, use lots of water with everything and you will continue to improve, but challenge yourself.
As far as the coughing, try keeping elevated some when resting/sleeping and experiment with using a humidifier to help keep yourself opened up. Not sure it will help you but couldn't hurt either.
Once again, Welcome smile
Steve
