My lab results that I received from my doctor are: elevated WBC 12.7, AST 68, ALT 116. they have increased in the last 6 weeks. I have a pin point red rash on my back, blurred vision, pain in my left lower back, sternal chest pain that goes under my left breast and pain on the top of my right breast, muscle weakness, fatigue, and I cant lay on my left side as it feels like something is pushing. CXR showed a mass, CT scan showed a mass in the superior mediastinal area. My doctor has not given me any diagnosis for this can you suggest what it might be. I am scheduled for a bronchoscopy on Tuesday.
