pulmonary embolism
"I had a PE in 2014. Will be on blood thinners for life. 
Specialist switched me from warfarin to Xarelto last February and life has been three shades of hell ever since.

Weight gain, pain, headaches, hair loss, ridiculous fatigue ... my period was out of control- like Carrie (stephen king) style until I finally got an IUD device (which I have never really wanted to do but at least my iron stores have recovered.)

I found a new family doctor who agreed to put me back on warfarin but the specialist talked me out of it this winter. 

I'm so weak and tired I can't stand it.

Started on warfarin yesterday and get to quit the Xarelto in two days. Can't wait."
