I am so sorry this happened to you. It's frustrating when "specialists" brush you off or don't listen. You want to RUN! I was told that my throat clearing by a specialist could just be a habit and possibly I may need to go for biofeedback. I didn't say anything because I clear my throat due to all this mucousy over production of saliva since Covid and allergies. I keep hearing about MA and I am going to do my research. Going to Long Covid Recovery Clinic soon. Stay tuned... Praying for you to find answers. God Bless You!
