Hi all. I'm trying to find out what's causing all of my symptoms. I have chest pain, eye pain & burning, skin rashes (sometimes painful), fatigue, sinus pain, headache, left ear ache, shortness of breath, occasional sore hands and feet, loss of appetite, and weight loss (no complaints with this sign). I have a history of asthma, allergies, IgA deficiency, mild chronic sinusitis, high lipoprotein (a), and mild tricuspid regurgitation.
