I am 60 years old. Since last 15 days, I have been suffering from -----burning in stomach, mild pain some times, after eating and drinking of water, I get burp and along this burp liquid comes out, some time with yellowish colour, some time it also contains food stuff which is eaten by me. Dry burp also comes. Since then I am also suffering with nose congestion, throat congestion. I have to pull the mucous of nose through throat. Because it does not come by nose blowing. Mucous also comes from throat. I am very much annoyed with this throat condition and congestion. Whether both these symptom of acidity and throat has any relation with each other. Dr. please help me. Dr. has given me biochemic 25 for remedy. Whether it is ok.
