My husband has had 2 nebulizer treatments (one yesterday & another approximately 2 hours ago. He states he has flashing lights in front of his eyes even though they are closed. He also had a tonic type tremor; could not communicate but could hear me speaking to him. This "tremor" lasted approx. 30 seconds. He felt like he had difficulty breathing. Pulse, O2 levels are good. Resp are short and shallow. BP is 124/64. He had a CXR today for severe, non productive cough that started over the weekend. PCP chose not to hospitalize him as his white counts are low due to chemo treatments. He's on antibiotics and seems to be feeling better except for this tremor activity. Please respond. We are not repeating the nebulizer treatment and will call the PCP in the morning.
