Hello, I have a number of concerning symptoms that just don t seem to go away- fatigue, diarrhea, red face, rashes on my arms that come and go (resemble pattechiae, but I think they come and go too fast to actually be), dizziness, fatigue, and swollen lymphnodes in my neck. I went to the doctor a few months ago, and blood work was normal except wbc were on the lower side of normal (4,000). Also yesterday, I was at dinner when my arms got so heavy I couldn t lift them, I had to sit back, and I couldn t speak. It only lasted 3-5 minutes, but it was really a scary feeling. Any thoughts on what this could be?
