My mom had a 4 week course of rituxan with one week cytoxan last month.
It has been 2 weeks since last dose and she is now on imuran.
Ever since starting the treatments, she has had this constant wheeze.
The wheeze is not in her lungs but sounds like it is somewhere between her neck and upper respiratory system.
Inhalers do not help it at all.
She only wheezes on exhale.
Her prior CT scan and xrays did not show any stenosis.
She has MPA determined by a kidney biopsy.
She has nodules and ground glass opacities in her lungs.

Could she have developed stenosis while on therapy?
Does this sound like stenosis and would an ENT be able to tell if there is narrowing?

Thanks
