I am hoping that someone can help me. I have been sick for about 3 months. My symptoms are varied. I have had a lot of muscle weakness, fatigue, nausea, coughing to the point of vomiting, & tiring easily. I went to the ER approximately 1 1/2 mths ago because my chest & back were aching so bad that I couldn't take it anymore. They did multiple tests. My oxygen was radiating between 54 & 82. They gave me a breathing treatment & put me on oxygen for 6 hrs. After doing a CT & other tests, they determined that I had a 7mm "ground glass nodule" in my right lung, elevated white blood count, blood in my urine, low sodium level, high potassium level, & inflammation in my lungs. My physician said that he would redo my CT in 6 mths. Well, I got extremely sick today with vomiting 4 times & I have began sleeping 14 hrs a day. I returned to the ER. (This time my fiance' didn't go "because I was wasting my time", all I have is a slight cold according to him). They repeated my CT & other tests. Everything stayed the same, however, I now have enlarged lymph nodes in my lung. Does this mean I need to be concerned? I feel like a "cry baby" & I am 44 yrs old!! I feel horrible, but I am about to give up & just go with my illness so I am not accused of "faking it".
