My husband had the flu about 9 weeks ago. He kept the cough when he got better. Then the cough turned into what he thought was coming from his sinuses. He went back to the doctor and she gave him nasal spray. The cough got worse. He returned and she said it was acid reflux.
He said he has a bad itch in the back of his throat and can't stop the cough. His mouth fills with water and he vomits.
I think it is a side effect of his high blood pressure medicine.
Sometimes coughs until his mouth fill with clear liquid and he throws up.
Today I looked in his throat and the roof of his mouth is white.
