I have a connective tissue disorder. Last week I thought I was having a flare up, flu like symptoms, joint pain, nausea, fatigue, etc. However, it progressively got worse, not better and I am having cold sweats, severe fatigue with minor activity, dizziness when I try to focus and continued nausea. I just feel like something is off. I am RN with a BSN, I have 11 years of Critical Care experience and have been trying not to read too much into in and thinking it will go away, but I really don t feel well.
