My husband has been suffering from a severe constant headache for abouut 4 months. He also had a onset of high blood pressure that has not been able to be controlled by medication. Other symptoms include night sweats, nausea, tightness in chest, tingling in hands, shakes at times and trouble sleeping, chronic pain. He has has had 2 Ekgs, A CAT scan and MRI of his head, stress test, several blood work ups, lyme disease test, mono test 2x, Hep test 2x, HIV test, Lupus and seveal other blood test at an infectious disease center that I am unsure of. ALL came back NORMAL. He does not drink or use any drugs. Over two weeks ago he had a CAT scan from his head to his pelvic area, this showed all his lymph nodes to be enlarged and his spleen to be enlarged. His doctor said he had a whole body problem and would have to under go more testing, we have no idea what this means and have not heard back, though we have left a message. We obviously are unsure and concerned and need direction on how to persue this. Should we sit back and wait or does this sound serious?
