I have SOB, tingling in my hands, nausea, dry mouth, and thirst (have had 4 large glasses of water and am still thirsty). I had sarcoidosis Dx ten years ago,and was on low flow O2 for about 2 1/2 years. Also very fatigued. I m a 70 year old white male, well nurished, with good medical care.
From your history you are suffering from OLD called acidosis. It causes fibrosis in lung tissue after pulmonary edema. Low O2 in blood is the main reason for breathlessness and fatigue. Get HRCT lung and pulmonary function test done to evaluate the lung condition. Only Chat Doctor.
