I have had fatigue, muscle weakness, chills, sweats, weight loss (12# in 5 weeks), swollen lymph nodes in neck, cough, headache, stomach pains, and other lesser symptoms for the past 6 months with no visible infection. Blood work(cbc, sedrate, b12) has all come back normal except high crp. Neck ct shows reactive nodes 6-9 mm in size throughout with more prominent nodes on right side. ENT says it isn't his problem to solve, Rheumatologist doesn't believe it is autoimmune related. Chest x-ray shows mass larger than a quarter on upper left side.
We have family history of cancer(breast, ovarian, prostate, lung)
Should I, as recommended, just continue to live with the fatigue and other symptoms and hope that in time it improves or should I seek further tests? What specialty doctor do I seek?
