HI , I'm nearly 4 yrs post Ivor lewis and recently had a pyloric dilation which has been a success. Today after gardening seem to have something stuck , with lots of burping and saliva. It feels a bit uncomfortable to swallow. Have tried fizzy drink, ice cream and yogurt in small amounts to try to dislodge but to no avail! How long do I carry on before ringing my Specialist nurse?
