A friend referred me to Dr Liang and I am grateful. She used to visit him for respiratory issues and she is a huge believer after she had a rather severe attack and he relieved her within moments of arriving at his office. I went for sinus infection issues and the dramatic change in my ability to breathe has been a huge relief for me. It took a year of using steroid nasal spray and having to use it every other day for me to get frustrated with the symptom suppressant and not the issue itself. Since I've started seeing Dr Liang I haven't had to use the spray once. His office is always booked and busy, so expect to wait a little bit and make sure to make an appointment ahead of time.
