I foster an autistic adult with developmental problems. She has lived with me for 10 years and always had a minor coughing tic. For the past year it has progressed into 125 coughs in 15 minutes and that was not counting her normal tic. We have tried antibiotics, allergy and meds, anti acid pills and luxopine. Currently, when she coughs she will also call my name. When I answer she acts like she didn't know she called me. I am going crazy with the constant cough because she also spits when she does it, no phlegm, just spit. Please help!!
