I have been so week and fatigue for months and it seems like it gets worse every week, I have had a lot of test ran and nothing has shown up. It feels like my body is not getting enough oxygen. my lymph nodes on my right side stay swollen and I am always dizzy. Saw an ENT and they didn't seem to concerned I am really concerned about my health. When I lay down my body gets real hot also. Does anyone have any insite on what could be going on.
