Sorry you have been so sick. I am no doctor but you may what to consult a rhem. I have some of your same symptoms. Have they done a ana blood test?
When I got sick, but looking back I had some symptoms before, the fatigue was terrible. Everyone kept telling me "well you work full time and have 5 kids you have a reason to be tired" but this is more that tired. no matter how much sleep, rest and care it never mad a difference". The rhem. was the first to really seem to understand what I was saying. I know lupus can effect all organs. I have trouble breathing at times feels like an weight is on my chest.
coughing blood would scare me to death, but I do know the lugs are and organ to. I had to female problems, this summer I had an overy removed and they did a hystorecomy. I did not want the hystorectomy, I wanted to try for one more. I have noticed that I don't have the constant labor pains that I use to have but I would have chosen to wait, given an option.
You might what to look around the other sights, rare disoders, ect.. I hope they find what is wrong. We are hear if you want to complain talk or need us.
keep me posted, I am concerned for you.
