My husband is 3 months post op Thyroid Cancer. Thyroid was removed as well as 6 metastatic nodes. 148 mc Radioactive Iodine was given & I131 scan showed only residual tissue. He currently takes his synthroid 150 mg. But it has been ineffective. 6 weeks ago he had an onset of pain in tailbone. Which has progressed to severe pain & inability to stand or walk correctly. Along with this his RBC Hemocrit & Hemoglobin levels are low, but his Platelet function times are elevated. He has had several CBC W/DIFF labs. His PFT has been up to 206- 247 ranges & his PFT EPI up to 179. They are consistently high with the exception of 2 different times being normal out of 6 draws. His ENT just removed tonsils with bleeding complications. He believes something is wrong & is sending him to Hematology at Vanderbilt. My question is could the bone pain be related to his levels? Lukemia? Or is that not usual or is it two separate issues such as a blood disorder and possibly a discount issue?
