Hi: I ve been having major swelling and pain associated with my lymph glands. I ve been to my specialist (I have already been diagnosed with Sjögren s syndrome appr. 10 years ago) and have been to Mayo Clinic for diagnosist testing last year with no results other than they believe I m in the early stages of another auto immune disease. That s my background which leads to this question. This week I ve been experiencing severe pain in spleen and into my rib and other lymph glands, I am having severe night sweats, not sleeping well and when I have the sharpest pain in my spleen, I seem to get very nauseated - should I be concerned? The severe pain and extreme nausea has been this week. Thank you
