Since being on Rituxan I have not had to have my windpipe stretched (3 to 4 times I had to have it done). I do have mucus/coughing in the mornings - usually I am able to take care of it within an hour of getting up. Talked to my ENT about the coughing- he said it was caused by the scaring from having the surgery. Can't complain - as long as I can breath. I have a new problem now - CLL. Took me off of Rituxan last year so I could start my chemo - I am worried about the complications from not being on Rituxan.
