I am experiencing recurring low grade fevers in the evening only. I have also have headaches, and an enlarged, painful cervical lymph note. I have lost 18 pounds over six months (without trying). However, I have recently been diagnosed with exocrine pancreatic insufficiency. There has been an improvement of constant diarrhea and LUQ pain since beginning pancreatic exocrine replacement therapy. CT of the chest, abdomen and pelvis was normal, as was CBC, U/A and many other tests. TSH was very low so my levothyroxine and cytomel were reduced. Any ideas?
