question: My mother is 88 yrs. old and is constantly couhging and chocking and seems to think it is due to sinus drainage but she chokes to the point of turning purple and it scares the daylights out of me. She does nt want to go to doc and seems to think that there is a med that will stop drainage.She used to take Copyronil that I guess worked but I m lost and don t like the ide of her choking to death. Any ideas?
