Have three doctors (family, neurologist, gastroenterologist) & seems they are communicating to each. feel they are not listening to me. what can i do?

Find a new dr: If you are not happy with your doctors, find a new one. No one is forcing you to keep them as your doctors. You are free to get a second opinion or change your physicians altogether.

They do communicate: First you have to give permission to talk to other doctor , your condition needs a team of doctors , they do communicate with each other, to give you the best possible care. If you feel they are not 'listening ' to you , express your concern first , that is not helping you then it is time to change the team . Add hope speaking to your doctors & questioning them helped you , good luck.
