These are the main symptoms i have been having the past 2 days i have a very strong sore throat that hurts even when im drinking water. My voice is completely gone even when i try yelling you can barely hear me. I don't get hungry but yes i am still eating (even though it hurts my throat). Very strong dizzyness when standing or when i have been on my feet a few minutes. Blistering headaches where i lose my vision and black out. I have no energy and my body feels super heavy like im made of lead. By these symptoms do any of you know what this is?
