Received a letter from Rheumatologist (copy of letter he sent to GP) saying my thyroid function showed "normal TSH at 0.52, normal free T3 at 4.6 but raised free T4 at 27.8. Cholesterol was 5.6. I feel very unwell and my morning temperature always in 35 degrees range. My GP has reduced Levo to 100 mcg from 125. Please could anyone comment on these results. Thank you for your help.
