My wife who is 28 years old is having sallowing problem. she faces difficulty while having her meal, juice, tea etc. While eating chapati or rice she has to drinks a lot of water to get it sallowed and sometime it's hard to drink water too. and when she try hard to sallow, it comes out with white foamy liquid. I am really worried and feel bad for my wife. kindly help how she can get over it. it's almost 6+ months now
