Hi I Am A 54 Yr Old Female With Hypothyriod,

hi i am a 54 yr old female with hypothyriod, recently diagnosed with an enlarged liver (still waiting on test results) recently have had weight gain regardless of eating habits, and abnormally exhausted within an hour of waking up. this morning i was horrified to wake up to both my feet being completely dark purple then noticed my hands were purple as well. the purple feet subsided within 5 minutes of standing and the hands a little after that. thoughts?
