waiting for nodule biopsy - low O2 readings
My pulmonologist has been tracking a lung nodule for 10 months. It's about 1.6 cm with multiple satellite nodules. He suspects non TB mycobaterial infection but differential includes rheumatoid nodules or malignancy. I've been coughing pretty badly for over three months now and he had me do a large dose of oral steroids and recently put me on a Symbicort inhaler. He scheduled a 3D robotic bronchoscopy to get a biopsy and that's in three weeks. In the meantime I've been tracking my pulse oxygen at home. It generally ranges between 94-98 but last night I got two readings of 92 and one of 93 and I wasn't feeling great at the time. This morning it was again 92. At what point should I call the pulmnonlogist's office?
