Hello Docs,My mother is suffering with food pipe problem. When she was small, she ate some acid like thing (accidently) due to which her food pipe contracted. Since then she is can swallow only if it s smaller than pea size. Thus, liquid like things or rice food is no problem but many times pea or similar like things have been stuck in which took hours to bring out with lot of pain. But since last two months it s worsen, that food pipe has become more thinner. She consulted some doctors and at present they put steel pipe like thing in her mouth to make the foodpipe bigger which cause lot of pain & sometime blood too comes. The throught swells up and the food pipe again contracts after 3-4 days. Doctors asked her to take this treatment (of steel pipe) in every 10 days for 2 months. Please, please help me.....
