Desaturated to 86 bilateral pins and needles in both hands and the technician had to call a doctor in. Apparently a sharp decrease in DLCO. A respiratory consultant I saw before told me to wear gloves when my hands turn blue, and a nurse accused me of exaggerating if not faking my breathing problems. Well, turns out they are real. Can't shower without getting out of breath anymore. Last spiro was ok according to consultant. Scared I will be on oxygen.
